R help - Oct 2012 - Error - function join()

Hi R-listers, 

In plyr I am using coding I have used before but an error seems to be
apparent. Has the function "join" been replaced by another word? I
tried
this before and it didn't work and then worked for me. But now it is not
working again. 

Please advise, Jean
> data.to.analyze <- join(responses, envir, by="QuadratEvent")
Error: could not find function "join"

I'm not sure there ever was a commonly used "join" function.
Perhaps
you are looking for one of

?merge
?rbind
?cbind

In particular, merge(,,by = "") seems right. But this doesn't have
anything to do with plyr so I might be misunderstanding you.
