It is generally expected that the questioner pose a specific example so the respondent can have some assurance they are answering the actual question. In this case please provide a test data set, intermediate results, and final result generated by your C program. It would also show that you made a reasonable effort if you showed what steps you tried in R and where you think they went wrong.
