i want to put the results of the list in a for loop

HI,

Not sure if I understand it clearly.

Are you looking for something like this:

res1<-list()
?fun1<-function(x,res){
?for(i in 1:ncol(x)){
?res[[i]]<-list()
?res[[i]]<-combn(1:ncol(x),i)
?}
?res}
fun1(m1,res1)

[[1]]
???? [,1] [,2] [,3] [,4] [,5]
[1,]??? 1??? 2??? 3??? 4??? 5

[[2]]
???? [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,]??? 1??? 1??? 1??? 1??? 2??? 2??? 2??? 3??? 3???? 4
[2,]??? 2??? 3??? 4??? 5??? 3??? 4??? 5??? 4??? 5???? 5
