R cbinding lists of data.tables

Question

I have two lists of data.tables of equal length in R. I want to element-wise cbind them. I sort of want to do a zip function where the input is two lists and the output is one list as illustrated below:

list1 list2                  list3
----- -----       ----------------
 dt1a  dt2a       cbind(dt1a,dt2a)
 dt1b  dt2b  =>   cbind(dt1b,dt2b)
 dt1c  dt2c       cbind(dt1c,dt2c)

What is the easiest way to do this?

Answer 1

list3 <- mapply(cbind, list1, list2, SIMPLIFY=FALSE)
