'Do I really need X11 for R on Mac?

R version 3.5.2

macOS version 10.14.2 mojave

Whenever installing an R, package I see the following warning:

Warning message:
In doTryCatch(return(expr), name, parentenv, handler) :
  unable to load shared object '/Library/Frameworks/R.framework/Resources/modules//R_X11.so':
  dlopen(/Library/Frameworks/R.framework/Resources/modules//R_X11.so, 6): Library not loaded: /opt/X11/lib/libSM.6.dylib
  Referenced from: /Library/Frameworks/R.framework/Resources/modules//R_X11.so
  Reason: image not found

Everything seems to work fine. ggplot2 plots get drawn,...etc.

Do I really need to install X11 from XQuartz? Is anything actually broken?

Does it "unlock" anything?
