I have some data in my C code, I want to execute chi-square test on those data. I tried implementing pchisq() function making use of header files R.h, Rhead.H and Rinternals.h, but it neither gave me the result nor threw any errors. It just returned 0 or 1. Could you please help me how can I implement those functions ? I am attaching the test-code herewith. ( For test purposes, I have been inputting the data here). http://www.nabble.com/file/p25788093/CforR.c CforR.c -- View this message in context: http://www.nabble.com/Help-with-pchisq-function-tp25788093p25788093.html Sent from the R help mailing list archive at Nabble.com.
