[R] Get the last 3 chars of a string

[Sergio Correia]

I want to extract the last 3 letters of a string.

So far, I've done this:

> symbol = 'XYZ.VX"
> substr(symbol,nchar(symbol)-2,nchar(symbol))
[1] ".VX"

It works, but the code looks UGLY as hell. Am I missing something? Or
is this the way it's supposed to be?

Thanks,
Sergio
