Try something like

for (ix in id) {
	fl[[basename(ix)]] <- list.files(ix)
But read R Inferno on inrementing objects first. It isn't efficient in memory terms (unless that's improved in recent versions of R)
Rather more elegantly you can get the same list with

sapply(id, function(ix) list.files(ix))
