This is going to be a really short one that I hope helps out some R users.
You might find when installing a package in R that you get something to the effect of
1package 'rgl' is not available
If you try to install it directly:
1install.packages('rgl')2...3# installation failed, X11 is not available
The first step is to install XQuartz.
Then, because the libraries and headers aren't installed to a location that
rgl's installation script looks for:
1options(configure.args = "--x-includes=/opt/X11/include --x-libraries=/opt/X11/lib")2install.packages("rgl")
This should get you to where you need to be. If not, please reach out my Twitter handle: @scottmmjackson and let me know.
