Splitting a set of vectors in a list
If I understand correctly, try this: as.data.frame(lapply(mylist, `[`, 1:max(unlist(lapply(mylist, length)))))

I have a set of character vectors of uneven length
that I have stored in a list. I can easily enough get
any column of them using lapply but what I want is to
be able to create a matrix of them. Other than some
kind of brute force looping approach I have drawn a
blank.
Would somebody please suggest something? Thanks
Example.
mylist <- list(aa=c("cat","peach" ), bb=c("dog",
"apple", "iron"),
cc = c("rabbit", "orange", "zinc", "silk"))
myfun <- function(dff) dff[1]
vect1 <- unlist(lapply(mylist, myfun))
