Re: [R] Step by step: Making an R package with Fortran 95
Thank you, Duncan. While your answers didn't quite fix my problems, I realized that I should probably go with the flow. I installed gfortran and everything worked fine. Thanks again.

[R] Step by step: Making an R package with Fortran 95
To all. I need your help. The big question is: How do I make an R library with Fortran 95 files? You may assume that I am a pretty decent programmer in both R and Fortran.

Suppose I'm using Windows XP and place the Folder for the package Testme in C:\Program Files\R\R-2.8.1\src\library\Testme I'd put your own files in their own directory, rather than in the R source tree.

Suppose that I have two *.f95 files, named CalculatorModule.f95 and ANiceSubroutine.f95. CalculatorModule.f95 contains a Fortran 95 module.
