Hello,
I have a list "ll - see below" on which I would like to apply a function
accessing every pair of elements in the list. For instance, I want to apply
the "sum" function on "6635 + 6636" and return the sum, the on "6635 +
6637", ...
Any hint to do that using apply / mapply / rapply ?
Thanks,
ll

[1] "6635" "6636"

[1] "6636" "6637"
sapply(ll, sum)
