Hello,
Here is a function that I wrote some time ago.
# pad with zeros
padz <- function(x, width=max(nchar(x)), fill="0")
gsub(" ", fill, formatC(x, width=width))
##------------- test
padz( c(1, 10, 100) )
padz(1:10, 4)
##------------- non-sense
padz(-5:0, 4)
padz(runif(10))
Hope this helps,
Rui Barradas

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
