prFindRownameMatches: Looks for unique rowname match without grep
Description
Since a rowname may contain characters reserved by regular
expressions I've found it easier to deal with the rowname
finding by just checking for matching strings at the beginning
of the name while at the same time excluding names that have the
same stem, i.e. DM and DM_COMP will cause an issue since DM will
match both rows.
Usage
prFindRownameMatches(rnames, vn, vars)
Arguments
rnames
A vector with the rownames that are looked for
vn
The variable name that is of interest
vars
A vector with all the names and the potentially competing names
Value
integer A vector containing the position of the matchesTODO: remove this function in favor of the more powerful prMapVariable2Name
