Arguments

tbl

table with antibiotic columns, like e.g. amox and amcl

col_mo

column name of the unique IDs of the microorganisms (see mo), defaults to the first column of class mo. Values will be coerced using as.mo.

info

print progress

rules

a character vector that specifies which rules should be applied - one or more of c("breakpoints", "expert", "other", "all")

verbose

a logical to indicate whether extensive info should be returned as a data.frame with info about which rows and columns are effected

amcl, amik, amox, ampi, azit, azlo, aztr, cefa, cfep, cfot, cfox, cfra, cfta, cftr, cfur, chlo, cipr, clar, clin, clox, coli, czol, dapt, doxy, erta, eryt, fosf, fusi, gent, imip, kana, levo, linc, line, mero, mezl, mino, moxi, nali, neom, neti, nitr, norf, novo, oflo, oxac, peni, pipe, pita, poly, pris, qida, rifa, roxi, siso, teic, tetr, tica, tige, tobr, trim, trsu, vanc

column name of an antibiotic, see Antibiotics

...

parameters that are passed on to eucast_rules

Source

Value

The input of tbl, possibly with edited values of antibiotics. Or, if verbose = TRUE, a data.frame with verbose info.

Antibiotics

To define antibiotics column names, input a text (case-insensitive) or use NULL to skip a column (e.g. tica = NULL). Non-existing columns will anyway be skipped with a warning.
