I do my devel/patch work on Mac so I can take a shot at testing your branch in the next couple days. ~G On Sun, Mar 29, 2020 at 7:24 PM Paul Murrell <paul at stat.auckland.ac.nz> wrote: > Hi > > I have created an R branch that contains a potential fix ... > > https://svn.r-project.org/R/branches/R-symfam/ > > This allows, for example, ... > >

Hi Thanks for your input on this I?aki and Nicolas. I am starting testing an R fix for this problem today. As suggested, the plan is to allow the R user to specify a font family other than "symbol" for plotmath output (or, more generally, in R parlance, for 'font=5' or 'fontface=5') on a Cairo-based graphics device.

Hi The R branch ... https://svn.r-project.org/R/branches/R-symfam/ ... is now set up so that it works "out of the box" on Fedora by setting the default to be 'symbolfamily=cairoSymbolFont(family, usePUA=FALSE)' when grSoftVersion()["pango"] is greater than "1.44". This means that on Fedora 31 (at least on the Docker container I am testing on)

Hi I have created an R branch that contains a potential fix ... https://svn.r-project.org/R/branches/R-symfam/ This allows, for example, ... cairo_pdf(symbolfamily="OpenSymbol") ... to specify that the OpenSymbol family should be used as the "symbol" font (e.g., for "plotmath") in R. This is just a separate branch for now because, while I have tested it under

Hi all, I have found after upgrading to R 4.0.0 (among other upgrades so this may not be the cause) that the degree symbol doesn't work correctly on Ubuntu 18.04. Googling brought me to this thread that appears related. I tried running: cairo_pdf() plot.new(); text(0.5,0.5, bquote(120*degree*N), cex=5) dev.off() and the ubuntu plot has the degree symbol vertically in the center of the line.

Hi Paul, I tried downgrading to R 3.4.4 and I still see the problem. I also have a conda environment that doesn't exhibit the problem so it's something environmental. Any tips for possible solutions/troubleshooting would be appreciated!

Paul et al, I will try to do this tonight or tomorrow, though it will not be built with th system tools because I have yet to get that tto work locally (spent a good chunk of this morning trying). I will send a separate messaage regarding those difficulties as well so that we can at least confirm that they are due to a malconfiguration on my part. Best, ~G On Tue, Apr 7, 2020 at 7:25 PM Paul
