问题
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?
回答1:
list3 <- mapply(cbind, list1, list2, SIMPLIFY=FALSE)
