Hello, I was able to create the Rdll.lib file. However, I get the following linking error message when I try to build my VC++ project.
The line that the linker is complaining about is calling the pnorm function. GenePoolAnalysis.obj : error LNK2019: unresolved external symbol _pnorm5 referenced in function... The offending line of code is PValue = 2*pnorm(-1.0*TestStatistic, 0.0, 1.0, 1, 0); Where you able to use R functions?
