Hi, Vissarion, If I understand your problem correctly, you can use "TYPEOF" from R's C API.
You can find more info on the type of an R object from https://cran.r-project.org/doc/manuals/r-release/R-ints.html#SEXPTYPEs The return value of this macro is an integer: https://github.com/wch/r-source/blob/master/src/include/Rinternals.h#L94-L126 Hadley also gives several examples in http://adv-r.had.co.nz/C-interface.html Best, KK On Sat, Oct 13, 2018 at 2:49 PM Vissarion Fisikopoulos <fisi...@gmail.com> wrote: > Hi, > > I am working on a rcpp project.
