Dear R users: Is there a way to append selectively to components of a list (if possible, loops are to be avoided)? To illustrate the point, in the example below, I would like to append 99 to vector b of the list l. > l <- list(a=c(1), b=c(2,3), c=c(4,5,6)) > l $a [1] 1 $b [1] 2 3 $c [1] 4 5 6 As you may expect, the result should look like: > l $a [1] 1 $b [1] 2 3 99 $c [1] 4 5
