\item{language}{language of the returned text, defaults to system language (see \code{\link[=get_locale]{get_locale()}}) and can also be set with \code{getOption("AMR_locale")}. Use \code{language = NULL} or \code{language = ""} to prevent translation.}
\item{tolower}{logical to indicate whether the first character of every output should be transformed to a lower case character. This will lead to e.g. "polymyxin B" and not "polymyxin b".}
\item An \code{\link{integer}} in case of \code{\link[=ab_cid]{ab_cid()}}
\item A named \code{\link{list}} in case of \code{\link[=ab_info]{ab_info()}} and multiple \code{\link[=ab_synonyms]{ab_synonyms()}}/\code{\link[=ab_tradenames]{ab_tradenames()}}
\item A \code{\link{double}} in case of \code{\link[=ab_ddd]{ab_ddd()}}
\item A \code{\link{character}} in all other cases
Use these functions to return a specific property of an antibiotic from the \link{antibiotics} data set. All input values will be evaluated internally with \code{\link[=as.ab]{as.ab()}}.
