< p > We will have to transform some variables to simplify and automate the analysis:< / p >
< ul >
< li > Microorganisms should be transformed to our own microorganism codes (called an < code > mo< / code > ) using < a href = "https://msberends.github.io/AMR/reference/catalogue_of_life" > our Catalogue of Life reference data set< / a > , which contains all ~70,000 microorganisms from the taxonomic kingdoms Bacteria, Fungi and Protozoa. We do the tranformation with < code > < a href = "../reference/as.mo.html" > as.mo()< / a > < / code > . This function also recognises almost all WHONET abbreviations of microorganisms.< / li >
< li > Antimicrobial results or interpretations have to be clean and valid. In other words, they should only contain values < code > "S"< / code > , < code > "I"< / code > or < code > "R"< / code > . That is exactly where the < code > < a href = "../reference/as.rsi.html" > as.rsi()< / a > < / code > function is for.< / li >
