I am new to R. I thing this will be simple, but I don't yet know my way around. 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.)

[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
