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.
