I will take a guess at what you want since you did not program an
example of your data or output desired:
> a <- 1:4
> b <- 1:6
> # get error message
> cbind(a,b)
a b
[1,] 1 1
[2,] 2 2
[3,] 3 3
[4,] 4 4
[5,] 1 5
[6,] 2 6
Warning message:
In cbind(a, b) :
number of rows of result is not a multiple of vector length (arg 1)
> # now combine them filling out with NAs
> combine <- list(a, b) # create a list of vectors to be bound
> max.length <- max(sapply(combine, length))
> do.call(cbind, lapply(combine, function(.vec){
+ c(.vec, rep(NA, max.length - length(.vec)))
+ }))
[,1] [,2]
[1,] 1 1
[2,] 2 2
[3,] 3 3
[4,] 4 4
[5,] NA 5
[6,] NA 6
