Jose,
If we assume that your character vector is saved in object 'a' then the
following line should do the job:
replace(a,which(nchar(a)==7),paste(0,a[nchar(a)==7],sep=""))

Dear S-Plus users,
I have a character column within a data set that has values with 7 and 8
characters of length.
Which is your recommended way to add a "0" at the left of those values
with
7 characters only?
Thanks in advance,
Jose
