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 the rest of the R code.
Is there a more efficient way to deal with NAs in C? I have used NAOK=true and sent them through using tobs=as.integer(tobs) for example, but when C looks at a NA it crashes. I am looking for the most efficient way to deal with NAs when they need to be sent to a C function. Any info here would be greatly appreciated!
