Hello,
try the following :
l <- list(NULL) l[[1]] <- 1:2 l[[2]] <- 2:3 l[[3]] <- 4:5 l
[[1]] [1] 1 2
[[2]] [1] 2 3
[[3]] [1] 4 5
matrix(unlist(l),ncol=2)
[,1] [,2] [1,] 1 3 [2,] 2 4 [3,] 2 5
Is that what you want ?

Hi
Sorry to ask such a basic question. I have a list, each element of which is a vector of two values. What I actually want is a matrix with two columns, and one row per element of the list. Obviously I have tried as.matrix(), and as.vector() but I didn't expect the latter to work.
I feel so lame asking this. Any suggestions?
Mick
