[R] transpose lists

[arun]

Hi,
You can try:
mat1<- do.call(rbind,x)
lapply(seq_len(ncol(mat1)),function(i) mat1[,i])
#[[1]]
#[1] 12.10  3.44

#[[2]]
#[1] 0.1 3.0

#[[3]]
#[1] 12.0 33.1

#[[4]]
#[1]  1.1 23.0


A.K.

Thanks. The result should be a list of lists like...

> x
[[1]]
[1] 12.10  3.44

[[2]]
[1] 0.1 3.0

[[3]]
[1] 12.0 33.1

[[4]]
[1]  1.1 23.0

lapply(x, t) doesn't do the job, I think.
