Loading List data into R with scan()

Try this:

 sapply(lapply(strsplit(l, ":"), strsplit, ","),
function(x)structure(lapply(x[2], as.numeric), .Names = x[1]))

Hi All,

I've been given a data file of the form:
1: 3,4,5,6
2:1,2,3
43: 5,7,8,9,5

and i want to read this data in as a list to create the form:
(guessing final look)
my.list
[[1]]
[1] 3 4 5 6

[[2]]
[1] 1 2 3

[[43]]
[1] 5 7 8 9 5

I can get to a stage using scan:
scan("my.data", what = character(0), quiet = TRUE)
to load
[1] "1: 3,4,5,6"
[2] "2:1,2,3"
[3] "43: 5,7,8,9,5"

but im not sure on how next to proceed to arrange this into a list form, can
anyone offer some advise?

Thanks in advance

Mike
