Not sure what "drawing a figure" actually means. Can you present code?

This error in Sierra hosted apps has also been reported on other app forums (as
well as once before on this mailing list Mon, 19 Dec 2016 by
a.becker...@sheffield.ac.uk but got no response):

I surely don't know about workarounds but this does appear to be specific to
Sierra. My MacbookPro is too old to get an update to Sierra. I do wonder if you
have an updated (or any) XQuartz and XCode? Generally a complete question will
include your versions of all essential system and R packages.
What does sessionInfo() return?
Try clicking on the system taskbar XQuartz icon and using `XQuartz/About X11`
and copying the version. I get:
XQuartz 2.7.11 (xorg-server 1.18.4)
My XCode version is: Version 8.2.1 (8C1002) but ISTR that Sierra needs a later
version.
And you should also probably indicate whether you have used either MacPorts or
homebrew.
The other system resource needed in the past was Tcl/Tk although I think that
now should get installed and attached by default with any current version of R.
The last link of the three above appeared related to the Tk interface which is
used by R.app and the tcltk package is part of the base installation, so might
be relevant, but this is written at the level of speculation. My other
hypothesis is that two different installations of Tcl/Tk might give problems on
one machine that were not encountered by others.
