How to install R-devel on Mac OS?

Question

I want to install R 4.0 for the newest Bioconductor submission. However, I cannot find instruction about the installation of R-devel for Mac OS, only the lists of prerequisites.

https://cran.r-project.org/doc/manuals/R-admin.html#macOS

Is there something I'm missing?

All help, including breaking down the task into smaller steps that can be mastered individually, are welcome.

Of this morning (26th of March 2020) the R 4.0.0 build is fixed and you can download the R-devel tar.gz from https://mac.r-project.org/

For the installation, I recommend following along the guide from RSwitch (https://rud.is/rswitch/guide/index.html).

1. Download the latest R-devel build:

wget https://mac.r-project.org/el-capitan/R-devel/R-devel-el-capitan-sa-x86_64.tar.gz

2. Unpack it at the root of your file system

sudo tar fvxz R-devel-el-capitan-sa-x86_64.tar.gz -C /

3. Open a new terminal and check if the installation was successful

~$ R --version
R Under development (unstable) (2020-03-25 r78063) -- "Unsuffered Consequences"
Copyright (C) 2020 The R Foundation for Statistical Computing
Platform: x86_64-apple-darwin15.6.0 (64-bit)

The nickname "Unsuffered Consequences" indicates that the installation was succesful.
