Numbers

You can easily write a simple function to do that:

letters2num <- function(x) {
	nletters <- 1:length(LETTERS)
	names(nletters) <- LETTERS
	nletters[x]
}
x <- c("A", "X", "F", "W", "G", "V", "L")
letters2num(x)
A  X  F  W  G  V  L 
 1 24  6 23  7 22 12

 Hi,

I know the function LETTERS, but, now I have some letters to 
convert it in numbers, like A=1,B=2, etc... Is any function 
to do that?

Atenciosamente,
