0.2.0.90xx (development version)

Support for Addins menu in RStudio to quickly insert %in% or %like% (and give them keyboard shortcuts), or to view the datasets that come with this package
For convience, descriptive statistical functions kurtosis and skewness that are lacking in base R - they are generic functions and have support for vectors, data.frames and matrices
New for frequency tables (function freq):
- A vignette to explain its usage
- Support for existing functions hist and plot to use a frequency table as input: hist(freq(df$age))
- Support for quasiquotation: freq(mydata, mycolumn) is the same as mydata %>% freq(mycolumn)
- Function top_freq function to return the top/below n items as vector
- Header of frequency tables now also show Mean Absolute Deviaton (MAD) and Interquartile Range (IQR)
- Possibility to globally set the default for the amount of items to print, with options(max.print.freq = n) where n is your preset value
Functions clipboard_import and clipboard_export as helper functions to quickly copy and paste from/to software like Excel and SPSS
Function g.test to perform the Χ² distributed G-test
Function ratio to transform a vector of values to a preset ratio (convenient to use with g.test). For example:

ratio(c(772, 1611, 737), ratio = "1:2:1")
# [1]  780 1560  780

Function p.symbol to transform p value to their related symbol: 0 '***' 0.001 '**' 0.01 '*' 0.05 '.' 0.1 ' ' 1

%like% now supports multiple patterns
Frequency tables are now actual data.frames with altered console printing to make it look like a frequency table. Because of this, the parameter toConsole is not longer needed.
Small translational improvements to the septic_patients dataset
Small improvements to the microorganisms dataset, especially for Salmonella
Combined MIC/RSI values will now be coerced by the rsi and mic functions:
- as.rsi("<=0.002; S") will return S
- as.mic("<=0.002; S") will return <=0.002
Now possible to coerce MIC values with a space between operator and value, i.e. as.mic("<= 0.002") now works
Added "groups" option for atc_property(..., property). It will return a vector of the ATC hierarchy as defined by the WHO. The new function atc_groups is a convenient wrapper around this.
Build-in host check for atc_property as it requires the host set by url to be responsive
Improved first_isolate algorithm to exclude isolates where bacteria ID or genus is unavailable
Fix for warning hybrid evaluation forced for row_number (924b62) from the dplyr package v0.7.5 and above
Support for 1 or 2 columns as input for guess_bactid
Fix for printing tibbles where characters would be accidentally transformed to factors

0.2.0 (latest stable version)

Full support for Windows, Linux and macOS
Full support for old R versions, only R-3.0.0 (April 2013) or later is needed (needed packages may have other dependencies)
Function n_rsi to count cases where antibiotic test results were available, to be used in conjunction with dplyr::summarise, see ?rsi
Function guess_bactid to determine the ID of a microorganism based on genus/species or known abbreviations like MRSA
Function guess_atc to determine the ATC of an antibiotic based on name, trade name, or known abbreviations
Function freq to create frequency tables, with additional info in a header
Function MDRO to determine Multi Drug Resistant Organisms (MDRO) with support for country-specific guidelines.
- Suggest your own via https://github.com/msberends/AMR/issues/new
- Exceptional resistances defined by EUCAST are also supported instead of countries alone
- Functions BRMO and MRGN are wrappers for Dutch and German guidelines, respectively
New algorithm to determine weighted isolates, can now be "points" or "keyantibiotics", see ?first_isolate
New print format for tibbles and data.tables

Fixed rsi class for vectors that contain only invalid antimicrobial interpretations
Renamed dataset ablist to antibiotics
Renamed dataset bactlist to microorganisms
Added common abbreviations and trade names to the antibiotics dataset
Added more microorganisms to the microorganisms dataset
Added analysis examples on help page of dataset septic_patients
Added support for character vector in join functions
Added warnings when a join results in more rows after than before the join
Altered %like% to make it case insensitive
For parameters of functions first_isolate and EUCAST_rules column names are now case-insensitive
Functions as.rsi and as.mic now add the package name and version as attributes

Expanded README.md with more examples
Added ORCID of authors to DESCRIPTION file
Added unit testing with the testthat package
Added build tests for Linux and macOS using Travis CI (https://travis-ci.org/msberends/AMR)
Added line coverage checking using CodeCov (https://codecov.io/gh/msberends/AMR/tree/master/R)
