<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><a href='https://rdrr.io/r/base/data.frame.html'>data.frame</a></code>, must have a column named <code>"mo"</code> which contains values from <code><a href='microorganisms.html'>microorganisms$mo</a></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://rdrr.io/r/base/options.html'>options(mo_source = path)</a></code>. Its timestamp will be saved with <code><a href='https://rdrr.io/r/base/options.html'>options(mo_source_datetime = ...)</a></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://rdrr.io/r/base/readRDS.html'>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><h3>How it works</h3>
