Hi
Everything works for me as expected. Nothing happens R starts as usual.
You can shorten your function
corregge2 <- function(stringa){
nc <- nchar(stringa)
stringa <- sub("^ ", "", stringa)
stringa <- sub(" +$", "", stringa)
if (nc <9) stringa <- NA
if (nc == 9) stringa <- paste("0",stringa,sep="")
if (nc == 10) stringa <- paste("00",stringa,sep="")
stringa
}
What if your string has length more than 10?
Regards
Petr
