Dear list,
I'm getting some false 'R CMD check' positives on rhub / Fedora: errors appearing on rhub that are not reproduced by CRAN. I have reported the matter here: https://github.com/r-hub/rhub/issues/92 It happens reproducibly for at least two of my packages: validate and lumberjack (I haven't tested any other yet). In short, knitr tries to open a png device while compiling a vignette and fails as follows. W checking re-building of vignette outputs Error in re-building vignettes: ... Warning in (function (filename = "Rplot%03d.png", width = 480, height = 480, : unable to open connection to X11 display '' It runs fine on R-devel, R-oldrel, R on windoze, solaris, centos, my own machines,..., and also on CRAN so it seems tied to rhub/Fedora. I have tried the following things already - Check whether R is called with xvfb-run (to simulate the X11 environment) in rhub's log. That's the case - Set up a minimal package with several vignettes and knitr settings, but I could not reproduce it minimally. If anyone has similar experiences it'd be nice to hear about it. Either for a workaround, or to gather some evidence that we can pass to Gabor, if it indeed is an rhub issue.
