Dear R,
Is there an efficient way to make a list that each element is from the
corresponding column of a matrix. For example, if I have a matrix "a"
> a <- matrix(1:10, 5, 2)
> a
[,1] [,2]
[1,] 1 6
[2,] 2 7
[3,] 3 8
[4,] 4 9
[5,] 5 10
I would like to have a list "b" like this
> b <- list(a[, 1], a[, 2])
> b
[[1]]
[1] 1 2 3 4 5
[[2]]
[1] 6 7 8 9 10
Thanks in advance!
