To have my plot match the font used for my writing, I added the font via the extrafont package. Thus, I performed the following procedure:
library(extrafont)
font_import()
loadfonts(device = "win")
This allowed me to change the font of my plot via a change of the theme. So far, so good. Now I want to export the plot using the ggsave() function. Unfortunately, the plot is exported without the new font, looking like this:
Output without font
However, I want it to look like this: Wanted look
Now, I read up and found some people with similar issues. However, none of the proposed solutions worked for me. I tried to use the jpeg() and png() functions, however, the resulting quality is extremely bad; even when changing size and dpi manually, it does not seem to have an effect.
Also, exporting as a pdf is not an option for me.
