My aim is to install the R package "quantreg". In R Studio, I therefore type
install.packages("quantreg")
R Studio then prints:
binary source needs_compilation
quantreg 5.85 5.88 TRUE
Do you want to install from sources the package which needs compilation? (Yes/no/cancel)
I consequently write "Yes" and hit enter. The installation then fails with the following output:
installing the source package ‘quantreg’

I am on Mac OS 12.3.1 Monterey and use R version 3.6.3. I use this old version of R (instead of an up-to-date one) because it is required in combination with another program that I use. Therefore, I cannot use newer versions of R.
What could be a possible fix for my problem, so that R installs quantreg without failing?
