[R-SIG-Mac] Problem installing RUcausal library on MAC

[varin sacha]

R-experts,

What is going wrong?

At the end of this page there is the installation command :
https://gitlab.science.ru.nl/gbucur/RUcausal/-/blob/master/README.Rmd 

Working with a MAC, I have tried to install the RUcausal library (copy and paste the installation command).

It is written that the package has been built on Linux using the GNU Compiler Collection. To install the package, open an R instance and run:
install.packages('devtools') # required package
devtools::install_git('https://gitlab.science.ru.nl/gbucur/RUcausal')

I get this error message :

  ERROR: package installation failed
Error: Failed to install 'RUcausal' from Git:
  ! System command 'R' failed
0d0bz2p4xg640000gn/T/RtmpMs1teQ/Rinst6453ee77bb8/RUcausal’



install.packages('devtools') # required package
