Rosana: As you say you are just beginning in R, it is probably worth adding that you should first take some time to learn basic R rules, one of which is that "legal" (i.e. syntactically valid) names in R cannot start with a number. See ?make.names for a brief discussion or an R tutorial -- as usual, there are many good ones on the internet.
