# Find and save information about fonts installed on your system
font_import()
# List the fonts
fonts()
After the one-time setup is done, there are tasks you need to do in each R session:
library(extrafont)
# Register the fonts for Windows
loadfonts(
"win"
)
Finally, you can create each output file or display graphs on screen, as in
Figure 14-5
:
library(ggplot2)
ggplot(mtcars, aes(x
=
wt, y
=
mpg))
+
geom_point()
+
ggtitle(
"Title text goes here"
)
+
theme(text
=
element_text(size
=
16
, family
=
"Georgia"
, face
=
"italic"
))
ggsave(
"myplot.png"
, width
=
4
, height
=
4
, dpi
=
300
)
