I still find the behavior of R's `for`-loop to be rather puzzling. In this case you appear to be getting the operation done, but because you didn't assign those table values to a variable they just disappeared. Try this: XXX <- list() for (i in 1:length(fuente)){ xxx=read_dta(fuente[i]) XXX[[i]] <- table(xxx$cise, xxx$sexo) rm(xxx) } str(XXX) Seems to me that if you can do assignment to the parent environment (without actually using assign( ..., env=...) that you should also be able to see the results of evaluation occurring inside the for loop, but for-loops return NULL. So you see nothing.
