add leading zeros
Much easier than you think:
x <- c(1L, 9000L)
sprintf("%05i",x)
Best,

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
