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':

I'm not sure why is this happening, any help? Thanks!
Cairo.capabilities() Details. The Cairo package provides multiple back-ends, such as images (PNG, JPEG, TIFF), vector graph- ics (PDF, PostScript, SVG) or displays (X11, Windows).
Cairo: R Graphics Device using Cairo Graphics Library for Creating High-Quality Bitmap (PNG, JPEG, TIFF), Vector (PDF, SVG, PostScript) and Display (X11 and Win32) Output.
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/
For anyone for whom installing XQuartz did not fix the problem:
Check the part of the error message that begins with "Library not loaded: ...". E.g., in the user's question, the error message contains this line:
dlopen(/Library/Frameworks/R.framework/Versions/3.3/Resources/library/Cairo/libs/Cairo.so, 6): Library not loaded: /opt/X11/lib/libXrender.1.dylib
Note this part:
Library not loaded: /opt/X11/lib/libXrender.1.dylib
That is the part that clues us in about XQuartz.
In my case, however, it specified that libjpeg
was not loaded, like this:
Error: package or namespace load failed for ‘Cairo’:
.onLoad failed in loadNamespace() for 'Cairo', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/usr/local/lib/R/3.5/site-library/Cairo/libs/Cairo.so':
dlopen(/usr/local/lib/R/3.5/site-library/Cairo/libs/Cairo.so, 6): Library not loaded: /usr/local/opt/jpeg/lib/libjpeg.9.dylib
Referenced from: /usr/local/lib/R/3.5/site-library/Cairo/libs/Cairo.so
Reason: image not found
Error: loading failed
Note this part:
Library not loaded: /usr/local/opt/jpeg/lib/libjpeg.9.dylib
To fix this, I had to run
brew unlink libjpeg; brew reinstall libjpeg
to get it working. I then had to do the same thing for libtiff:
brew unlink libtiff; brew reinstall libtiff
After fixing both of those libraries, running install.packages("Cairo")
worked.
