[R] Loop over folder files

[ruipbarradas at sapo.pt]

Hello,

Where does read_dta come from? You should also post the library() instruction.
Try to run the code without the loop, with just one file and inspect  
xxx to see what's happening.

xxx <- read_dta(fuente[1])
str(xxx)
table(xxx$cise, xxx$sexo)
