The following might be what you want (replace "clipboard" with your
filename):
> mylist <- strsplit(readLines("clipboard"), ":")
> nm <- sapply(mylist, "[", 1)
> mylist <- lapply(mylist, "[", -1)
> names(mylist) <- nm
> mylist <- lapply(mylist, function(s) strsplit(s, ",")[[1]])
> mylist
$entry0001
[1] "AB0032" "CF32134" "DF34334"
$entry0002
[1] "AB0033"
$entry0003
[1] "AB0032" "CF32134" "DF34334" "DD343434" "DD34222"
$entry0004
[1] "AB0032" "CF32134"
