You are citing a 3 year-old message that had multiple contributors.  
Either it wasn't answered by Dalgaard or your question is different.   
May I suggest that you use that message as a template for constructing  
a proper R-help question, i.e. one that has a cut-and-pastable input  
and specifies the desired output?

the current code is like this
vidx-grep(paste('^',vars[vi],'$',sep=''),gsub([[:punct:]],,strrl1[[datbeg-1]]),ignore.case=T)

where as the old one was
vidx-grep(vars[vi],gsub([[:punct:]],,strrl1[[datbeg-1]]),ignore.case=T)
