Hi Peter,

Thanks for the response. What you've suggested works fine but I'm  
looking
for something that is simpler than my solution and avoids the pesky  
warning
message. Your response avoids the warning message but just as  
complex (if
not more). I just assumed there would be a function along the lines  
of:

mydata <- c("A", "C", "A", "D", "B", "B")
reclassify(mydata, inCategories=c("A", "B" ,"C", "D"),
 outCategories=c("Group1", "Group1", "Group2", "Group2"))

[1] "Group1" "Group2" "Group1" "Group2" "Group1" "Group1"

But of course, except sometimes you have to write the function  
yourself.

reclassify = function(data, inCategories, outCategories)
{
  outCategories[ match(data, inCategories)]
}

Sorry I can't make it any simpler than a 1-line solution :)
