为 Rstudio 安装 package rms 时遇到问题

Question

I have been having an issue installing package rms. I am trying to interpret ordinal models (using the package ordinal) and plot regressions using them. For rms, I don't even get an error, just that it updates other loaded packages, loads and attaches package 'lubridate' which had already been installed, and that 'date' is masked from the base package.

For reference I had originally tried to install hmisc, which I found out was a dependency for rms. This led to an issue installing dependency gfortran. When I attempt to install gfortran, I get

  package ‘gfortran’ is not available (for R version 3.5.1)

But then, when I try to install Hmisc, I get

installing the source package ‘Hmisc’

For reference, I run this on a Mac OS Catalina (10.15.4).

Alternatively, if you have any other ways to graph regressions using ordinal models please let me know. Thank you very much.

I got a similar error even though I had installed gfortran by running brew install gfortran . But I needed to add this to my ~/.Rprofile :

Sys.setenv(PATH="/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin")
