My reproducible issue looked resolved (as I posted) when I upgraded to 10.15.5.
Today I found another issue, but not repeatable so I haven't posted it yet. this is the headline: > car::scatter3d(RRS ~ CCS + JCS, + data=RespJ$variables, + surface=FALSE, residuals=TRUE, bg="white", + axis.scales=TRUE, grid=TRUE, ellipsoid=FALSE, + point.col="black") Loading required namespace: mgcv error: xp_attach_gl_context returned: 2 *** caught segfault *** address 0x18, cause 'memory not mapped' Traceback: 1: rgl.open(useNULL) 2: open3d() 3: .check3d() 4: rgl::next3d() 5: scatter3d.default(X[, 2], X[, 1], X[, 3], xlab = xlab, ylab = ylab, zlab = zlab, radius = radius, id = id, ...) 6: scatter3d(X[, 2], X[, 1], X[, 3], xlab = xlab, ylab = ylab, zlab = zlab, radius = radius, id = id, ...) 7: scatter3d.formula(RRS ~ CCS + JCS, data = RespJ$variables, surface = FALSE, residuals = TRUE, bg = "white", axis.scales = TRUE, grid = TRUE, ellipsoid = FALSE, point.col = "black") 8: car::scatter3d(RRS ~ CCS + JCS, data = RespJ$variables, surface = FALSE, residuals = TRUE, bg = "white", axis.scales = TRUE, grid = TRUE, ellipsoid = FALSE, point.col = "black") Possible actions: 1: abort (with core dump, if enabled) 2: normal R exit 3: exit R without saving workspace 4: exit R saving workspace Selection: 4 Warning message: In rgl.open(useNULL) : RGL: ERROR: can't bind glx context to window Process R exited abnormally with code 71 at Mon Jun 1 13:53:39 2020 On Mon, Jun 1, 2020 at 20:02 Joseph Vanterpool <jvanterpool1...@gmail.com> wrote: > Hello, > > Yesterday, I started using the John Hopkins course that includes R > training.
