try this:
split(dat, dat$class)
where 'dat' is your data.frame
I hope it helps.
Best, Dimitris

Subject: [R] more classes to one class in one dataset
I have a big database which more classes in class variable. I want to make each class to one dataset, for example: x1 x2 x3 x4 class a b a c c M1 c b b c c M4 c c a c c M2 c a c a a M2 c c a a a M1 c a b c a M3 c c a b c M3 c a c a b M2 c c a b a M1
How can I make, like:
x1 x2 x3 x4 class a b a c c M1 c c a a a M1 c c a b a M1
x1 x2 x3 x4 class c c a c c M2 c a c a a M2 c a c a b M2
x1 x2 x3 x4 class c a b c a M3 c c a b c M3
x1 x2 x3 x4 class c b b c c M4
Thanks for your help. Jan Sabee
