<p>We’ve got a new website: <ahref="https://msberends.gitlab.io/AMR/">https://msberends.gitlab.io/AMR</a> (built with the great <ahref="https://pkgdown.r-lib.org/"><code>pkgdown</code></a>)</p>
<ul>
<li>Contains the complete manual of this package and all of its functions with an explanation of their parameters</li>
<li>Contains a comprehensive tutorial about how to conduct antimicrobial resistance analysis, import data from WHONET or SPSS and many more.</li>
<strong>BREAKING</strong>: removed deprecated functions, parameters and references to ‘bactid’. Use <code><ahref="../reference/as.mo.html">as.mo()</a></code> to identify an MO code.</li>
<li>Catalogue of Life as a new taxonomic source for data about microorganisms, which also contains all ITIS data we used previously. The <code>microorganisms</code> data set now contains:
<li>All ~3,000 (sub)species from these orders of the kingdom of Fungi: Eurotiales, Onygenales, Pneumocystales, Saccharomycetales and Schizosaccharomycetales (covering at least like all species of <em>Aspergillus</em>, <em>Candida</em>, <em>Pneumocystis</em>, <em>Saccharomyces</em> and <em>Trichophyton</em>)</li>
<li>All ~2,000 (sub)species from ~100 other relevant genera, from the kingdoms of Animalia and Plantae (like <em>Strongyloides</em> and <em>Taenia</em>)</li>
This data is updated annually - check the included version with the new function <code><ahref="../reference/catalogue_of_life_version.html">catalogue_of_life_version()</a></code>.</li>
<li>Due to this change, some <code>mo</code> codes changed (e.g.<em>Streptococcus</em> changed from <code>B_STRPTC</code> to <code>B_STRPT</code>). A translation table is used internally to support older microorganism IDs, so users will not notice this difference.</li>
<li>Support for data from <ahref="https://whonet.org/">WHONET</a> and <ahref="https://ecdc.europa.eu/en/about-us/partnerships-and-networks/disease-and-laboratory-networks/ears-net">EARS-Net</a> (European Antimicrobial Resistance Surveillance Network):
<li>Exported files from WHONET can be read and used in this package. For functions like <code><ahref="../reference/first_isolate.html">first_isolate()</a></code> and <code><ahref="../reference/eucast_rules.html">eucast_rules()</a></code>, all parameters will be filled in automatically.</li>
<li>This package now knows all antibiotic abbrevations by EARS-Net (which are also being used by WHONET) - the <code>antibiotics</code> data set now contains a column <code>ears_net</code>.</li>
<li>The function <code><ahref="../reference/as.mo.html">as.mo()</a></code> now knows all WHONET species abbreviations too, because almost 2,000 microbial abbreviations were added to the <code>microorganisms.codes</code> data set.</li>
<p>The <code>antibiotics</code> data set will be searched, after which the input data will be checked for column names with a value in any abbreviations, codes or official names found in the <code>antibiotics</code> data set. For example:</p>
<aclass="sourceLine"id="cb2-4"title="4"><spanclass="co"># Filtering on glycopeptide antibacterials: all of `vanc` and `teic` is R</span></a></code></pre></div>
These functions use <code><ahref="../reference/as.atc.html">as.atc()</a></code> internally. The old <code>atc_property</code> has been renamed <code><ahref="../reference/atc_online.html">atc_online_property()</a></code>. This is done for two reasons: firstly, not all ATC codes are of antibiotics (ab) but can also be of antivirals or antifungals. Secondly, the input must have class <code>atc</code> or must be coerable to this class. Properties of these classes should start with the same class name, analogous to <code><ahref="../reference/as.mo.html">as.mo()</a></code> and e.g.<code>mo_genus</code>.</li>
<li>New functions <code><ahref="../reference/mo_source.html">set_mo_source()</a></code> and <code><ahref="../reference/mo_source.html">get_mo_source()</a></code> to use your own predefined MO codes as input for <code><ahref="../reference/as.mo.html">as.mo()</a></code> and consequently all <code>mo_*</code> functions</li>
<li>New function <code><ahref="../reference/as.mo.html">mo_failures()</a></code> to review values that could not be coerced to a valid MO code, using <code><ahref="../reference/as.mo.html">as.mo()</a></code>. This latter function will now only show a maximum of 10 uncoerced values and will refer to <code><ahref="../reference/as.mo.html">mo_failures()</a></code>.</li>
<li>New function <code><ahref="../reference/as.mo.html">mo_uncertainties()</a></code> to review values that could be coerced to a valid MO code using <code><ahref="../reference/as.mo.html">as.mo()</a></code>, but with uncertainty.</li>
<li>New function <code><ahref="../reference/as.mo.html">mo_renamed()</a></code> to get a list of all returned values from <code><ahref="../reference/as.mo.html">as.mo()</a></code> that have had taxonomic renaming</li>
<li>New function <code><ahref="../reference/age.html">age()</a></code> to calculate the (patients) age in years</li>
<li>New function <code><ahref="../reference/age_groups.html">age_groups()</a></code> to split ages into custom or predefined groups (like children or elderly). This allows for easier demographic antimicrobial resistance analysis per age group.</li>
<p>New function <code><ahref="../reference/resistance_predict.html">ggplot_rsi_predict()</a></code> as well as the base R <code><ahref="https://www.rdocumentation.org/packages/graphics/topics/plot">plot()</a></code> function can now be used for resistance prediction calculated with <code><ahref="../reference/resistance_predict.html">resistance_predict()</a></code>:</p>
<p>Functions <code><ahref="../reference/first_isolate.html">filter_first_isolate()</a></code> and <code><ahref="../reference/first_isolate.html">filter_first_weighted_isolate()</a></code> to shorten and fasten filtering on data sets with antimicrobial results, e.g.:</p>
<li>New function <code><ahref="../reference/availability.html">availability()</a></code> to check the number of available (non-empty) results in a <code>data.frame</code>
</li>
<li><p>New vignettes about how to conduct AMR analysis, predict antimicrobial resistance, use the <em>G</em>-test and more. These are also available (and even easier readable) on our website: <ahref="https://msberends.gitlab.io/AMR"class="uri">https://msberends.gitlab.io/AMR</a>.</p></li>
<li>Updated EUCAST Clinical breakpoints to <ahref="http://www.eucast.org/clinical_breakpoints/">version 9.0 of 1 January 2019</a>, the data set <code>septic_patients</code> now reflects these changes</li>
<li>Fixed a critical bug where some rules that depend on previous applied rules would not be applied adequately</li>
<li>Emphasised in manual that penicillin is meant as benzylpenicillin (ATC <ahref="https://www.whocc.no/atc_ddd_index/?code=J01CE01">J01CE01</a>)</li>
<li>New info is returned when running this function, stating exactly what has been changed or added. Use <code><ahref="../reference/eucast_rules.html">eucast_rules(..., verbose = TRUE)</a></code> to get a data set with all changed per bug and drug combination.</li>
<li>Removed data sets <code>microorganisms.oldDT</code>, <code>microorganisms.prevDT</code>, <code>microorganisms.unprevDT</code> and <code>microorganismsDT</code> since they were no longer needed and only contained info already available in the <code>microorganisms</code> data set</li>
<li>Added 65 antibiotics to the <code>antibiotics</code> data set, from the <ahref="http://ec.europa.eu/health/documents/community-register/html/atc.htm">Pharmaceuticals Community Register</a> of the European Commission</li>
<li>Removed columns <code>atc_group1_nl</code> and <code>atc_group2_nl</code> from the <code>antibiotics</code> data set</li>
<li>Functions <code><ahref="../reference/AMR-deprecated.html">atc_ddd()</a></code> and <code><ahref="../reference/AMR-deprecated.html">atc_groups()</a></code> have been renamed <code><ahref="../reference/atc_online.html">atc_online_ddd()</a></code> and <code><ahref="../reference/atc_online.html">atc_online_groups()</a></code>. The old functions are deprecated and will be removed in a future version.</li>
<li>Function <code><ahref="../reference/AMR-deprecated.html">guess_mo()</a></code> is now deprecated in favour of <code><ahref="../reference/as.mo.html">as.mo()</a></code> and will be removed in future versions</li>
<li>Function <code><ahref="../reference/AMR-deprecated.html">guess_atc()</a></code> is now deprecated in favour of <code><ahref="../reference/as.atc.html">as.atc()</a></code> and will be removed in future versions</li>
<p>Uncertainty of the algorithm is now divided into four levels, 0 to 3, where the default <code>allow_uncertain = TRUE</code> is equal to uncertainty level 2. Run <code><ahref="../reference/as.mo.html">?as.mo</a></code> for more info about these levels.</p>
Using <code><ahref="../reference/as.mo.html">as.mo(..., allow_uncertain = 3)</a></code> could lead to very unreliable results.</li>
<li>All microbial IDs that are found with zero uncertainty are now saved to a local file <code>~/.Rhistory_mo</code>. Use the new function <code><ahref="../reference/as.mo.html">clean_mo_history()</a></code> to delete this file, which resets the algorithms.</li>
<li>
<p>Incoercible results will now be considered ‘unknown’, MO code <code>UNKNOWN</code>. On foreign systems, properties of these will be translated to all languages already previously supported: German, Dutch, French, Italian, Spanish and Portuguese:</p>
<aclass="sourceLine"id="cb9-3"title="3"><spanclass="co"># one unique value (^= 100.0%) could not be coerced and is considered 'unknown': "qwerty". Use mo_failures() to review it.</span></a>
<li>Fixed a bug where distances between dates would not be calculated right - in the <code>septic_patients</code> data set this yielded a difference of 0.15% more isolates</li>
<li>Will now use a column named like “key(…)ab” or “key(…)antibiotics” for the key antibiotics (parameter <code>col_keyantibiotics()</code>), when this parameter was left blank</li>
<li>A note to the manual pages of the <code>portion</code> functions, that low counts can influence the outcome and that the <code>portion</code> functions may camouflage this, since they only return the portion (albeit being dependent on the <code>minimum</code> parameter)</li>
<li>Reduce false positives for <code><ahref="../reference/as.rsi.html">is.rsi.eligible()</a></code> using the new <code>threshold</code> parameter</li>
<li>Summaries of class <code>mo</code> will now return the top 3 and the unique count, e.g.using <code><ahref="https://www.rdocumentation.org/packages/base/topics/summary">summary(mo)</a></code>
</li>
<li>Small text updates to summaries of class <code>rsi</code> and <code>mic</code>
<divclass="sourceCode"id="cb10"><preclass="sourceCode r"><codeclass="sourceCode r"><aclass="sourceLine"id="cb10-1"title="1"><spanclass="co"># Determine genus of microorganisms (mo) in `septic_patients` data set:</span></a>
<aclass="sourceLine"id="cb10-2"title="2"><spanclass="co"># OLD WAY</span></a>
<li>Added header info for class <code>mo</code> to show unique count of families, genera and species</li>
<li>Now honours the <code>decimal.mark</code> setting, which just like <code>format</code> defaults to <code><ahref="https://www.rdocumentation.org/packages/base/topics/options">getOption("OutDec")</a></code>
</li>
<li>The new <code>big.mark</code> parameter will at default be <code>","</code> when <code>decimal.mark = "."</code> and <code>"."</code> otherwise</li>

</li>
<li>Function <code>count_all</code> to get all available isolates (that like all <code>portion_*</code> and <code>count_*</code> functions also supports <code>summarise</code> and <code>group_by</code>), the old <code>n_rsi</code> is now an alias of <code>count_all</code>
</li>
<li>Function <code>get_locale</code> to determine language for language-dependent output for some <code>mo_*</code> functions. This is now the default value for their <code>language</code> parameter, by which the system language will be used at default.</li>
<li>Data sets <code>microorganismsDT</code>, <code>microorganisms.prevDT</code>, <code>microorganisms.unprevDT</code> and <code>microorganisms.oldDT</code> to improve the speed of <code>as.mo</code>. They are for reference only, since they are primarily for internal use of <code>as.mo</code>.</li>

</li>
<li>
<code>EUCAST_rules</code> was renamed to <code>eucast_rules</code>, the old function still exists as a deprecated function</li>
<li>Now also applies rules from the EUCAST ‘Breakpoint tables for bacteria’, version 8.1, 2018, <ahref="http://www.eucast.org/clinical_breakpoints/"class="uri">http://www.eucast.org/clinical_breakpoints/</a> (see Source of the function)</li>
<li>New parameter <code>rules</code> to specify which rules should be applied (expert rules, breakpoints, others or all)</li>

</li>
<li>Fewer than 3 characters as input for <code>as.mo</code> will return NA</li>
<li>Added parameter <code>combine_IR</code> (TRUE/FALSE) to functions <code>portion_df</code> and <code>count_df</code>, to indicate that all values of I and R must be merged into one, so the output only consists of S vs.IR (susceptible vs.non-susceptible)</li>

<li>Added parameter <code>also_single_tested</code> for <code>portion_*</code> and <code>count_*</code> functions to also include cases where not all antibiotics were tested but at least one of the tested antibiotics includes the target antimicribial interpretation, see <code><ahref="../reference/portion.html">?portion</a></code>
<li>Using <code>portion_*</code> functions now throws a warning when total available isolate is below parameter <code>minimum</code>
</li>
<li>Functions <code>as.mo</code>, <code>as.rsi</code>, <code>as.mic</code>, <code>as.atc</code> and <code>freq</code> will not set package name as attribute anymore</li>

<li>The data set <code>microorganisms</code> now contains <strong>all microbial taxonomic data from ITIS</strong> (kingdoms Bacteria, Fungi and Protozoa), the Integrated Taxonomy Information System, available via <ahref="https://itis.gov"class="uri">https://itis.gov</a>. The data set now contains more than 18,000 microorganisms with all known bacteria, fungi and protozoa according ITIS with genus, species, subspecies, family, order, class, phylum and subkingdom. The new data set <code>microorganisms.old</code> contains all previously known taxonomic names from those kingdoms.</li>
<li>Functions <code>count_R</code>, <code>count_IR</code>, <code>count_I</code>, <code>count_SI</code> and <code>count_S</code> to selectively count resistant or susceptible isolates
<li>Extra function <code>count_df</code> (which works like <code>portion_df</code>) to get all counts of S, I and R of a data set with antibiotic columns, with support for grouped variables</li>
<li>Function <code>is.rsi.eligible</code> to check for columns that have valid antimicrobial results, but do not have the <code>rsi</code> class yet. Transform the columns of your raw data with: <code>data %>% mutate_if(is.rsi.eligible, as.rsi)</code>
<p>Functions <code>as.mo</code> and <code>is.mo</code> as replacements for <code>as.bactid</code> and <code>is.bactid</code> (since the <code>microoganisms</code> data set not only contains bacteria). These last two functions are deprecated and will be removed in a future release. The <code>as.mo</code> function determines microbial IDs using intelligent rules:</p>
