R Question

include cairo R on a mac

I'm trying to use 'Cairo' package in Rstudio, using the command

install.packages('Cairo')

and it goes through with no problem.
I get this message-

The downloaded binary packages are in
/var/folders/xn/c1nj85gx62b89876s15sbv9h0000gn/T//RtmpK9JM0l/downloaded_packages


The package appears in the packages list, but when I try to include the package using
library(Cairo)
or
library('Cairo')

I get this error mesage-

Error : .onLoad failed in loadNamespace() for 'Cairo', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.3/Resources/library/Cairo/libs/Cairo.so':

You should download X11 for Mac, which is called XQuartz. It doesn't ship with OS X any more, so you have to download it separately from: https://www.xquartz.org/
