dear R family,i have a matrix of 444 columns. what i want to do is the following.
1. starting from column 1 i want to select every 37th column on the way. more precisely i want to select column 1, 38,75,112,149 and so on.
2.starting from column 2, i again want to select every 37th column. which means 2,39,76,113,150 and so on.
similarly starting from 3 till 37th column.
i have tried following loop command which is not working.can anyone plz see whats wrong in that?
for (i in 1:37)

{

a<-e[,e[i]:444]

}

lapply(seq_len(1),
function(i) {

a[,c(TRUE, rep(FALSE,1))]

})
extremly sorry for bothering you once again..
