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

Dear R users,
i want to put the results of a list to a for loop.
i will give an example
m1<-matrix(rep(1,15),ncol=5)
ind.sgn <- lapply(1:ncol(m1), combn, x = ncol(m1))
ind.sgn
[[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
[[3]]
[,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9] [,10]
[1,] 1 1 1 1 1 1 2 2 2 3
[2,] 2 2 2 3 3 4 3 3 4 4
[3,] 3 4 5 4 5 5 4 5 5 5

[4,] 4 5 5 5 5
[[5]]
[,1]
[1,] 1
[2,] 2
[3,] 3
[4,] 4
[5,] 5
I want in any of theses results to put them in for loop
each time to multiply a column as indicates the list. for example
first it will multiply each column
after will multiply two columns as in [[2]]
after will multiply three columns as in [[3]]etc
any help will be welcome
