How to change the default font in ggplot 2

Hi!

I want to change the font of my scatterplot created with ggplot2 and use Arial as font.
I did first check the default font so I did:

windowsFonts()

And I get:

$serif
[1] "TT Times New Roman"

$sans
[1] "TT Arial"

$mono
[1] "TT Courier New"

So this means that the default font it Times New roman? if so, how do I change it with Arial?
If I understood correctly, I should use extrafont package but when I try to import the fonts it doesn’t work (it gives me No FontName. Skipping error). here my code:

install.packages("extrafont")
library(extrafont)
font_import()

So I did try use an older version of Rttf2pt1 :

library(remotes)
remotes::install_version("Rttf2pt1", version = "1.3.8")

and it loaded OK but when I try to import the font I get:

Scanning ttf files in C:WINDOWSFonts ...
Extracting .afm files from .ttf files...
Error in ttf_extract(ttfiles) : 
  lazy-load database 'N:/R/win-library/4.1/Rttf2pt1/R/Rttf2pt1.rdb' is corrupt
In addition: Warning message:
In ttf_extract(ttfiles) : internal error -3 in R_decompress1

so I am not sure what I am doing wrong but I am also not sure this is the best way to do since all the post I’ve found are pretty old so maybe new fast method/package exist.

Can you help me with this error or do you know if there is a simpler way to change the font in ggplot2?

Thank you!
