Использование sysfonts от Google в ggplot2

/ 29 февраля 2020

Я пытаюсь выяснить, как добавить Google Fonts в ggplot2 с пакетом sysfonts (или другим способом). Я могу их достаточно легко с extrafont, но есть ли у кого-нибудь рабочий процесс, чтобы добавить их с sysfonts? Ниже приводится то, что у меня есть: 

library(ggplot2)
library(extrafont)
#> Registering fonts with R
#font_import() ## takes a while to run
loadfonts(device = "win")
#> Agency FB already registered with windowsFonts().
#> Algerian already registered with windowsFonts().
...
#> Vivaldi already registered with windowsFonts().
#> Vladimir Script already registered with windowsFonts().
#> Webdings already registered with windowsFonts().
#> Wingdings already registered with windowsFonts().
#> Wingdings 2 already registered with windowsFonts().
#> Wingdings 3 already registered with windowsFonts().


ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
  ggtitle("Fuel Efficiency of 32 Cars") +
  xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
  theme(text=element_text(size=16,  family="Lucida Console"))




library(sysfonts)
font_add_google('Yanone Kaffeesatz')

ggplot(mtcars, aes(x=wt, y=mpg)) + geom_point() +
  ggtitle("Fuel Efficiency of 32 Cars") +
  xlab("Weight (x1000 lb)") + ylab("Miles per Gallon") +
  theme(text=element_text(size=16,  family="Yanone Kaffeesatz"))

Создано в 2020-02-28 представьте пакет (v0.3.0)

Очевидно, что второй график не был создан с помощью шрифта Google. Есть идеи?
