I was preparing an editors/TeXmacs update and noticed that the R plugin had graphs with missing glyphs. Here is a diff for R to do what Ze Loff suggested in these two threads[2][3]. Fix taken from [1]. sthen@ described the root cause in [2] but consider this workaround. This diff: - changes the site-wide config (/usr/local/lib/R/library/base/R/Rprofile) to use DejaVu Sans by default. - updates README to document that the font can be changed - bumps REVISION sources: [1] https://stackoverflow.com/questions/1189759/expert-r-users-whats-in-your-rprofile [2] https://marc.info/?l=openbsd-ports&m=157830898518255&w=2 [3] https://marc.info/?l=openbsd-ports&m=159342491019196&w=2 I was able to run these two test plots with the TeXmacs R plugin, math/rstudio and with R itself. test 1: demo(plotmath) mash enter a few times test 2: qnorm(1/2,mean=0,sd=1) x<-1:100 y<-rnorm(x) plot(x,y) Feedback and tests are welcome.
