Unable to load emojifont

[jblumenau]

I'm having trouble loading emojifont:

> library(emojifont)
Error: package or namespace load failed for ‘emojifont’:
 .onLoad failed in loadNamespace() for 'sysfonts', details:
  call: dyn.load(file, DLLpath = DLLpath, ...)
  error: unable to load shared object '/Users/uctqebl/Library/R/3.4/library/sysfonts/libs/sysfonts.so':
  dlopen(/Users/uctqebl/Library/R/3.4/library/sysfonts/libs/sysfonts.so, 6): Library not loaded: /opt/X11/lib/libfreetype.6.dylib
  Referenced from: /Users/uctqebl/Library/R/3.4/library/sysfonts/libs/sysfonts.so
  Reason: image not found

Any idea what might be going on? Here's the sessionInfo:

Same here!

this is due to the issue of your sysfonts installation.

try:

require(sysfonts)

I had this same issue (with both emojifont and sysfonts), and found I had to install Xquartz. Then the issue went away. Found that answer here, but reposting for the next person.
