Hi,
Think I might be misunderstanding what you want, because ...
> t = "0000123"
> as.integer(t)
[1] 123
anyway
> t = "0000123"
> substr(t,regexpr("[^0]",t),nchar(t))
[1] "123"
seems to trim the leading 0's

Subject: [R] Truncating leading zeros in strings
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?
Thanks
Paul
