如何从 R extrafontdb 中注销已删除的字体

Question

I have loaded my fonts using

library(extrafont)
font_import()

When I look at the path using

fonttable()

There are some fonts which does not exist any longer under that path. This creates some problems for me later on. How do I remove/unregister them from the font database?

Just rerunning font_import does not work.

Answer 1

It's easy, just run the following code:

db_path <- paste0(system.file(package = "extrafontdb"),"/fontmap/fonttable.csv")
file.show(db_path)

This will open up a .csv file where you can just remove the fonts you want to unregister. Save the file when you're done and voilá!
