What should I do in this case? It seems I need to install a missing font but I don't know which font.

davidgohel commented 7 years ago

You can see what are available fonts by running the following command:

gdtools::sys_fonts()

The column family contains family names.

Then in the ggiraph call, add the parameter fonts as below (see rvg::dsvg for more details):

ggiraph(..., fonts = list(sans = "a_sansserif_font", serif = "a_serif_font", mono = "mono_font", symbol = "symbol_font"))

The following vignette is explaining things better than I do: https://CRAN.R-project.org/package=svglite/vignettes/fonts.html (dsvg do not handle user font aliases for now).

> gdtools::sys_fonts()
Fontconfig error: Cannot load default config file
[1] foundry family  file    slant   weight 
<0 rows> (or 0-length row.names)

After googling for a while, this could be caused by the OS not on R side. I haven't found the solution yet but closed the case.

Thank for your help.

davidgohel commented 7 years ago

OK

That thread may help: https://groups.google.com/forum/#!topic/reporters-package/9WP5uqP2hr8

In short: "I had to update HomeBrew and install the cairo package manually"
