I have seen this question here: Error in loading rgl package with Mac OS X but there is no mentioning about installation error, which is my case. I cannot install rgl<
On Ubuntu 16.04 and 18.04, you might get this issue when trying to install rgl
from CRAN:
checking for X... no configure: error: X11 not found but required, configure aborted.
ERROR: configuration failed for package ‘rgl’
Credit is due to this blog which solved my problems at installing rgl
:

In case the link above disappears, the solution, as outlined in the blog is:
sudo apt-get install xorg
sudo apt-get install libx11-dev
sudo apt-get install libglu1-mesa-dev
More recently, installing rgl on a fresh ubuntu 16.04 install also requires a further step (as noted in the comments below), if you get this error:
fatal error: ft2build.h: No such file or directory
This is solved with:
sudo apt-get install libfreetype6-dev
Then installing rgl
from CRAN should just work.
Not sure about Mac case but on Windows I faced issues downloading the same rgl Package. Installing the RGL requires the devtools package
install.packages("devtools")
library(devtools)
install.packages("rgl")
library(rgl)
Took me a long time to figure this out on the [RHEL 3.10.0-862.14.4.el7.x86_64 x86_64 x86_64 x86_64 GNU/Linux]. The following packages are required:
libpng12-devel.x86_64
ImageMagick-c++-devel.x86_64
mesa-libGLU-devel.x86_64
libselinux-devel.x86_64
xorg-x11-apps
All the mentioned answers are correct; however, none is for Mac.
In my case (I am a Mac user), I solved the problem by installing XQuartz and restarting R.
On OpenSuse
sudo zypper install xorg-x11-devel
sudo zypper install glu-devel
On Ubuntu, what worked for me was to install the package directly from the command line:
sudo apt-get install r-cran-rgl
(We have a strange setup here, so YMMV)
