}
%- maybe also 'usage' for other objects documented here.
\arguments{
  \item{catIDs}{ a character vector containing category IDs }
  \item{catType}{ type of category }
  \item{strict}{ logic value to stop conversion if NA is introduced. }
  \item{missing}{ type of handling NA mapping. }
  \item{nameLength}{ show how many first letters for long term names, 'all' for full name }
  \item{addID}{ logic, add term IDs following term names or not}
}
\details{
  The current version only supports 'GO', 'DOLite' and 'KEGG'.
  There are three types of parameters for variable 'missing'. 'name' means the NA mapping values are replaced by their names. 'keep' means all of NA values are kept. 'remove' means all of NA values are removed.
