I am having issues in installing the samr package in R v3.4 MacOS sierra. I get this warning message: 

  "Package which is only available in source form, and may need compilation of
   C/C++/Fortran: ‘samr’
 Do you want to attempt to install these from sources?
 y/n: y

Warning in install.packages :

Does anybody has an idea to overcome this?

  • This means that you need gfortran compiler. – Consistency May 28 '17 at 14:31
  • You could try: https://gcc.gnu.org/wiki/GFortranBinaries – Consistency May 28 '17 at 14:33
  • See: https://cran.r-project.org/bin/macosx/tools/ – MrFlick May 28 '17 at 14:38
  • It's a good idea to get gfortran directly from CRAN (see above), because each version of R is built to work with a particular version of gfortran (which is usually not the newest one included with gcc). Using other versions is a common source of more confusing package installation bugs. – alistaire May 28 '17 at 17:33
