# S3 method for GenericDataFileSet
indexOf(this, patterns=NULL, by=c("exact", "regexp", "fixed"), ...,
onMissing=c("NA", "error"))Returns an integer
vector of length K with elements in
[1,*length()] or (integer) NA (for non-matched names).
Henrik Bengtsson
If an element of patterns contains a comma, then that element
is matched against the *getFullNames(), otherwise it is
matched against *getNames().
First each pattern is matched by regular expression rules, and if
there is not match, then by fixed strings.
*getNames()
