add leading zeros

Hi Josh,
Check ?formatC and ?sprintf for some options.

Hi all,
    Trying to use an apply to add leading zeros to a set of values in a
given vector.  I only want to add enough zeros so that the total number of
characters is 5, so if I have an element "1" i want "00001" or "9000" I want
"09000".  I tried

vec <- 1:1000
sapply(vec, FUN = sprintf(paste("%0",(5-nchar(x)),"d",sep=""),x))

but she doesnt work.  I struggle with the apply family for sure.  Thanks

Josh
