Hi,
I have several matrix in a list, for example:
e
[[1]]
[,1] [,2]
[1,] 1 3
[2,] 2 4
[[2]]
[,1] [,2]
[1,] 1 4
[2,] 2 5
[3,] 3 6
[[3]]
[,1] [,2]
[1,] 2 1
I would like to join them by column i.e.
[,1] [,2] [,3] [,4][,5] [,6]
[1,] 1 3 1 4 2 1
[2,] 2 4 2 5 NA NA
[3,] NA NA 3 6 NA NA
I have tried do.call(cbind,e) but I get this error message as the rows are
of different length-
Error in function (..., deparse.level = 1) :
number of rows of matrices must match (see arg 2)
Can anyone advise me please?
Thanks Emma
