.. and you will end up - in your example- with 60 t-statistics and
p-values (so you do bonforroni adjustment or something like that)?!
Sometimes the question for "How do I ..." should be read as "What is
the question I *really* want to be answered ...". You may consider doing
some more sophisticated analysis.

Hi R users,
I have a very large data set that has two conditioning variables for the
test I want to perform.
A toy set can be simulated:
type<-sample(1:3,100,replace=TRUE)
class<-sample(1:20,100,replace=TRUE)
value<-rnorm(100)
data<-cbind(type,class,value)
(though type and class are alphanum)
I want to perform the three pair-wise t-tests between types for each
class in data.
Can someone help me out with this?
Any help is greatly appreciated.
Dan
