[R] Dealing with NAs in C

Hi. I am currently converting a lot of R code to C in order to make it more efficient. A lot of the data involves NAs. As the data is mainly integers > 0, I am just setting all NAs to 0 then sending it to the C code then resetting them to NAs again after the C program is done, to be compatible with
