Unable to successfully install rayshader from GitHub or CRAN

Hi Tyler,

I have tried many ways to install rayshader. First, I tried to get install the GitHub version so that I had access to the most up-to-date version, but this failed:

remotes::install_github('tylermorganwall/rayshader')

ERROR: lazy loading failed for package ‘rayshader’
* removing ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rayshader’
* restoring previous ‘/Library/Frameworks/R.framework/Versions/3.6/Resources/library/rayshader’
Error: Failed to install 'rayshader' from GitHub:
  (converted from warning) installation of package ‘/var/folders/1q/l_382_ss2973kpyqn0sk_0lw0000gn/T//RtmpO4lurM/file433950fd11a2/rayshader_0.13.1.tar.gz’ had non-zero exit status

I have not been able to yet troubleshoot the above error.

So I tried instead to download the CRAN version:

install.packages('rayshader')

This seemingly installed successfully, but when loading the package:

library(rayshader)

Error: package or namespace load failed for ‘rayshader’ in dyn.load(file, DLLpath = DLLpath, ...):
 unable to load shared object '/Library/Frameworks/R.framework/Versions/3.6/Resources/library/imager/libs/imager.so':

  Referenced from: /Library/Frameworks/R.framework/Versions/3.6/Resources/library/imager/libs/imager.so

Seems to be an issue with the imager package, which I have removed and installed a few times but hasn't seemed to help.

Yikes, sorry about that. Installing XQuartz totally fixed it. New computer, forgot to install it when I set everything up.

Thanks.
