* Removed `as.integer()` for MIC values, since MIC are not integer values and running `table()` on MIC values will consequently fail for not being able to retrieve the level position (as that's how normally `as.integer()` on `factor`s work)
* `droplevels()` on MIC will now return a common `factor` at default and will lose the `<mic>` class. Use `droplevels(..., as.mic = TRUE)` to keep the `<mic>` class.

<li>The <ahref="./reference/microorganisms.html">data set microorganisms</a> contains the complete taxonomic tree of ~70,000 microorganisms. Furthermore, some colloquial names and all Gram stains are available, which enables resistance analysis of e.g.different antibiotics per Gram stain. The package also contains functions to look up values in this data set like <code><ahref="reference/mo_property.html">mo_genus()</a></code>, <code><ahref="reference/mo_property.html">mo_family()</a></code>, <code><ahref="reference/mo_property.html">mo_gramstain()</a></code> or even <code><ahref="reference/mo_property.html">mo_phylum()</a></code>. Use <code><ahref="reference/mo_property.html">mo_snomed()</a></code> to look up any SNOMED CT code associated with a microorganism. As all these function use <code><ahref="reference/as.mo.html">as.mo()</a></code> internally, they also use the same intelligent rules for determination. For example, <code>mo_genus("MRSA")</code> and <code>mo_genus("S. aureus")</code> will both return <code>"Staphylococcus"</code>. They also come with support for German, Danish, Dutch, Spanish, Italian, French and Portuguese. These functions can be used to add new variables to your data.</li>
