Hello,
I would like to reshape my data for presentation purposes from something
like this:
> test <-
data.frame(a=c("A","A","A","A","B","B","B"),b=c(1,1,2,2,1,1,1),c=1:7)
> test
a b c
1 A 1 1
2 A 1 2
3 A 2 3
4 A 2 4
5 B 1 5
6 B 1 6
7 B 1 7
to something like this:
a b c
1 A 1 1,2
3 A 2 3,4
5 B 1 5,6,7
This seems to be the sort of the thing that the reshape library should
be able to do, but I just can't work out how to do it.
Many thanks
Dan
