[R] Loop over folder files

[Juan Ceccarelli Arias]

I just doesn't work...
Im loading the read,dta13 package already.
When i try to perform a simple table(sex), i received the "File not found"
message.
However, if i load the data using the file.choose() option inside
read.dta13, i can open the stata file.
I don't know what am i doing wrong...
