I don't have an answer, but there were a bunch of tk-functions that were removed in version 3.0.0, including: tkcmd(), tkfile.dir(), tkfile.tail(), tkopen(),tkputs(), tkread()

There was also a news() item that specifically mentioned tkrplot and changes to the Windows graphics devices but didn't appear to me to imply anychanges to tkrplot.

Something very similar was reported 

	From: 	Natalija Keck <Natalija.Keck at the-klu.org>
	Subject: 	[R-SIG-Mac] loading issue with tkrplot on OS X Yosemite
	Date: 	May 4, 2015 5:22:37 AM PDT
	To: 	r-sig-mac R <r-sig-mac at r-project.org>

I don't see a response in my local email "not-an-Archive".

I get the same result after installing tkrplot 0.0-23 from CRAN (using the binary pkg and installing with the R.app Package Instller)  and running R from a terminal session. XQuartz loads and then the seg-fault dialog appears. I've got XQuartz 2.7.7 (xorg-server 1.15.2) and the "check for updates" response for a running X11 session says I have the latest version.
