Combining (cbind) vectors of different length

by

You can use indexing, if you index a number beyond the size of the object it returns NA. This works for any arbitrary number of rows defined with foo:

nm <- list(1:8,3:8,1:5)

foo <- 8

sapply(nm, '[', 1:foo)

EDIT:

Or in one line using the largest vector as number of rows:

sapply(nm, '[', seq(max(sapply(nm,length))))

From R 3.2.0 you may use lengths (“get the length of each element of a list”) instead of sapply(nm, length):

sapply(nm, '[', seq(max(lengths(nm))))
