Hi, Using the R C PAI, is there a way to convert to convert STRSXP or INTSXP to factor.
The idea would be to do in C something similar to the "factor" function (example below): > letters[1:5] # [1] "a" "b" "c" "d" "e" > factor(letters[1:5]) # [1] a b c d e # Levels: a b c d e There is the function setAttrib the levels of a SXP however when returned to R the object is of type character not factor. Ideally what i would like to return from the C function is the same output as above when the input is of type character. Please let me if you need more informations.
