I've just upgraded R to version 4.0.0.
When I try to install the package with the following command
install.packages("redshiftTools",repos = c("http://rstudio.org/_packages","http://cran.rstudio.com"))
I am getting the following error:
Warning in install.packages :
package ‘redshiftTools’ is not available (for R version 4.0.0)
Warning in install.packages :
unable to access index for repository http://rstudio.org/_packages/bin/windows/contrib/4.0:
cannot open URL 'http://rstudio.org/_packages/bin/windows/contrib/4.0/PACKAGES'
Is it possible to still install it and get my scripts to work?
