<p>These functions can be used to predefine your own reference to be used in <code><a href='as.mo.html'>as.mo</a></code> and consequently all <code>mo_*</code> functions like <code><a href='mo_property.html'>mo_genus</a></code> and <code><a href='mo_property.html'>mo_gramstain</a></code>.</p>
<p>This is <strong>the fastest way</strong> to have your organisation (or analysis) specific codes picked up and translated by this package.</p>

<table class="ref-arguments">
<colgroup><col class="name" /><col class="desc" /></colgroup>
<tr>
<th>path</th>
<td><p>location of your reference file, see Details</p></td>

</table>
<h2 class="hasAnchor" id="details"><a class="anchor" href="#details"></a>Details</h2>
<p>The reference file can be a text file seperated with commas (CSV) or tabs or pipes, an Excel file (either 'xls' or 'xlsx' format) or an R object file (extension '.rds'). To use an Excel file, you need to have the <code>readxl</code> package installed.</p>
<p><code>set_mo_source</code> will check the file for validity: it must be a <code>data.frame</code>, must have a column named <code>"mo"</code> which contains values from <code>microorganisms$mo</code> and must have a reference column with your own defined values. If all tests pass, <code>set_mo_source</code> will read the file into R and export it to <code>"~/.mo_source.rds"</code>. This compressed data file will then be used at default for MO determination (function <code><a href='as.mo.html'>as.mo</a></code> and consequently all <code>mo_*</code> functions like <code><a href='mo_property.html'>mo_genus</a></code> and <code><a href='mo_property.html'>mo_gramstain</a></code>). The location of the original file will be saved as option with <code><a href='https://www.rdocumentation.org/packages/base/topics/options'>options</a>(mo_source = path)</code>. Its timestamp will be saved with <code><a href='https://www.rdocumentation.org/packages/base/topics/options'>options</a>(mo_source_datetime = ...)</code>.</p>
<p><code>get_mo_source</code> will return the data set by reading <code>"~/.mo_source.rds"</code> with <code><a href='https://www.rdocumentation.org/packages/base/topics/readRDS'>readRDS</a></code>. If the original file has changed (the file defined with <code>path</code>), it will call <code>set_mo_source</code> to update the data file automatically.</p>
<p>Reading an Excel file (<code>.xlsx</code>) with only one row has a size of 8-9 kB. The compressed file used by this package will have a size of 0.1 kB and can be read by <code>get_mo_source</code> in only a couple of microseconds (a millionth of a second).</p>
<h2 class="hasAnchor" id="how-it-works"><a class="anchor" href="#how-it-works"></a>How it works</h2>
<p>Imagine this data on a sheet of an Excel file (mo codes were looked up in the `microorganisms` data set). The first column contains the organisation specific codes, the second column contains an MO code from this package:</p><pre>
| A | B |
--|--------------------|-------------|
1 | Organisation XYZ | mo |
2 | lab_mo_ecoli | B_ESCHR_COL |
3 | lab_mo_kpneumoniae | B_KLBSL_PNE |
4 | | |
</pre>
<p>We save it as <code>'home/me/ourcodes.xlsx'</code>. Now we have to set it as a source:</p><pre>
set_mo_source("home/me/ourcodes.xlsx")
# Created mo_source file '~/.mo_source.rds' from 'home/me/ourcodes.xlsx'.
</pre>
<p>It has now created a file "~/.mo_source.rds" with the contents of our Excel file, but only the first column with foreign values and the 'mo' column will be kept.</p>
<p>And now we can use it in our functions:</p><pre>
as.mo("lab_mo_ecoli")
[1] B_ESCHR_COL
mo_genus("lab_mo_kpneumoniae")
[1] "Klebsiella"
# other input values still work too
as.mo(c("Escherichia coli", "E. coli", "lab_mo_ecoli"))
[1] B_ESCHR_COL B_ESCHR_COL B_ESCHR_COL
</pre>
<p>If we edit the Excel file to, let's say, this:</p><pre>
| A | B |
--|--------------------|-------------|
1 | Organisation XYZ | mo |
2 | lab_mo_ecoli | B_ESCHR_COL |
3 | lab_mo_kpneumoniae | B_KLBSL_PNE |
4 | lab_Staph_aureus | B_STPHY_AUR |
5 | | |
</pre>
<p>...any new usage of an MO function in this package will update your data:</p><pre>
as.mo("lab_mo_ecoli")
# Updated mo_source file '~/.mo_source.rds' from 'home/me/ourcodes.xlsx'.
[1] B_ESCHR_COL
mo_genus("lab_Staph_aureus")
[1] "Staphylococcus"
</pre>
<p>To remove the reference completely, just use any of these:</p><pre>
set_mo_source("")
set_mo_source(NULL)
# Removed mo_source file '~/.mo_source.rds'.
</pre>
