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.
Thank you
Best regards
Morgan
