如何解决extrafont中的错误状态5？

Question

My aim is to use the font xkcd.tff . I checked that it's installed in the dir

C:/Users/prgca/AppData/Local/Microsoft/Windows/Fonts

once I

font_import(path = "C:/Users/prgca/AppData/Local/Microsoft/Windows/Fonts",
             pattern = "xkcd")

This is the output

Scanning ttf files in C:/Users/prgca/AppData/Local/Microsoft/Windows/Fonts ...
Extracting .afm files from .ttf files...
C:\Users\prgca\AppData\Local\Microsoft\Windows\Fonts\xkcd.ttf : No FontName. Skipping.

The font is, indeed, not loaded into my plots. How can I load it?

Answer 1

I suspect this is related to issues with Rttf2pt1 (upon which extrafont depends) as described here and here . Suggested solution which worked for me is to downgrade Rttf2pt1 as below:

remove.packages("Rttf2pt1")   
remotes::install_version("Rttf2pt1", version = "1.3.8")
