This is really odd, and probably 100% local to me, but I'm at a loss as to a next step.
After narrowing things down, here's how to reproduce: library("rgl") showSomething <- function() { open3d() points3d(rnorm(10),rnorm(10),rnorm(10)) axes3d() title3d('main','sub','xlab','ylab','zlab') } showSomething() # works as expected. # Close the current rgl window showSomething() # crashes R with the following report: *** caught segfault *** address 0x0, cause 'unknown' Traceback: 1: .C(rgl_dev_open, success = FALSE) 2: rgl.open() 3: open3d() 4: showSomething() This will probably work fine for any of you, it's so simple and fundamental. If I don't close the open rgl windows, it doesn't crash, and I can execute the function over and over successfully. And the same thing happens if I just do the commands inside the function individually. SessionInfo() below. Perhaps something is corrupt with my X11 window system?
