RandomFields is a dependency needed for the NLMR package. Neither of these are on cran anymore so I am trying to download older versions by downloading RandomFields first and then my plan is to download NLMR.
I've downloaded older versions of packages before using
install_github("cran/RandomFields") or
install_version("RandomFields", "3.3.14").
The issue that I am running into is with my C++ compiler. When I run either of the lines of code above, I get ERROR: compilation failed for package ‘RandomFields’:
> install_version("RandomFields", "3.3.13")

Warning in i.p(...) :
I already have xtools installed and following this forum, am trying to set up gfortram. I have successfully installed homebrew (brew.sh/) on my computer, but when I try and run - brew install gcc on my terminal, I get the following:
error: Not a valid ref: refs/remotes/origin/master
fatal: ambiguous argument 'refs/remotes/origin/master': unknown revision or path not in the working tree.
Use '--' to separate paths from revisions, like this:
'git <command> [<revision>...] -- [<file>...]'
Running `brew update --auto-update`...
fatal: Could not resolve HEAD to a revision
Warning: No available formula with the name "gcc".

Error: No similarly named formulae found.

Error: No previously deleted formula found.

Error: No formulae found in taps.
My understanding is that gfortran is no longer provided separate of gcc, so you have to set up gcc first in order to set up gfortran but I don't know enough about coding in my terminal to know what to do now.
My main goal is to get the NLMR and RandomFields packages working on my computer, so if there is a way to do this without addressing the compiler issue, please let me know!
Session info:
I am running a macOS Monterey Version 12.3.1
R version 4.2.0 (2022-04-22)
RStudio Version 1.4.1725
Please let me know if I can clarify anything and thanks in advance for your time!
