Cannot install dREG with R 4.0 because rphast is no longer in CRAN

[omsai]

According to the rphast package page on CRAN:

Package ‘rphast’ was removed from the CRAN repository.

Formerly available versions can be obtained from the archive.

Archived on 2020-03-03 as check problems were not corrected despite reminders.

A summary of the most recent check results can be obtained from the check results archive.

Please use the canonical form https://CRAN.R-project.org/package=rphast to link to this page.

Workaround until the dependency is replaced:

remotes::install_url("https://cran.r-project.org/src/contrib/Archive/rphast/rphast_1.6.9.tar.gz")

An aletrnative for anyone that might run into the same issue (as happened to me): it is also possible to install ‘rphast’ directly from R, using devtools 'devtools::install_github("CshlSiepelLab/RPHAST")' as indicated here.
