Thanks... As I mentioned, I am new to R, and "as.integer" was not
what I stumbled onto. I looked up string conversion in the reference
manual, and "strtoi" is what came up.

I am generating character strings from the system clock that
represent integers, and I want to convert them to integer values.
Strtoi works well, except when there are leading zeros on the
string. Could anyone suggest a way to remove those leading zeros?
as.integer doesn't work? (If you are dealing in different base than
10, then you really should say so.)
> as.integer("0000123")
[1] 123
Or pass through sub("^[0]+", "", vals)
> sub("^[0]+", "", "0000123")
[1] "123"
An example is expected in such situations. Please do now read the
