Multicross no longer valid for New R Versions

[JyoRoy21]

The multicross package seems to be no longer available in CRAN and as a result I am not able to download SCPA. I am not sure how to go about it. Following is the error I get when I run: devtools::install_version("multicross", version = "2.1.0", repos = "http://cran.us.r-project.org") I have tried manually uploading the package by downloading from CRAN archive but it doesn't work as well.

Hi,

It looks like this is an issue with Fortran. Your error says:

sh: /opt/gfortran/bin/gfortran: No such file or directory

You need to install the GNU Fortran compiler. You can get this from the R installation instructions here https://archive.linux.duke.edu/cran/. Click on Download R for MacOS > then follow the link to the Fortran compiler.

I was initially using SCPA in my old R and it was working fine. But early 2024 I updated it and since then SCPA is no longer downloadable due to the mismatch of multicross package with the new version. It seems like multicross package has been removed and not available for the current versions of R. Can something be done about it

Hi,

The issue isn't with multicross. The issue comes from your newer version of R that relies on having the GNU Fortran compiler installed for packages that use Fortan code. nbpMatching uses Fortran, so you need to install the GNU Fortran compiler
