Re: [R] reading stata files: preserving values of variables converted to factors

Thanks for the clarification.  I found the labels  values in

attributes(dataframe)$label.table$varname

which looks the same whether convert.factors is TRUE or FALSE.

 factor levels (looking at the output of unclass(varname)), so the

 Yes. The R factor type should not be used if you want the original 
 levels. It is not a 'labelled numeric' type and the numbers are an 
 implementation detail.
 
  Using convert.factors=FALSE
 preserves the values, but seems to discard the labels.
 
 It doesn't discard the labels. They are kept in the attributes of the 
 data frame.

[R] reading stata files: preserving values of variables converted to factors

preserves the values, but seems to discard the labels.  Is it possible 
to get these variables into R while preserving both the values and the 
labels?

Thanks,
