Thanks. formatC(flag) works.
But it's awefully slow. I try to do that for 65000 numbers (generating ID
for each item) and it seems like forever.
On my not that recent laptop:
> system.time(formatC(1:65000, width=10, flag="0"))
user system elapsed
1.92 0.00 1.94
I think 2 seconds is less than "forever".

Is there any faster way?
Thank all.

Hi,
What's one way to convert an integer to a string with preceding 0's?
such that
'13' becomes '00000000013'
to be put into a string
I've tried formatC, but they removes all the zeros and replace it with
blanks
Not so for me:
formatC(13, digits=10, flag="0")

Thanks
