Playing with fonts

OK, so I couldn't download the xkcd font through R on my mac.
I had to download the font by going to the webpage and then I could install it on the mac.

Then,
font_import(pattern = "[X/x]kcd", prompt=FALSE)
fonts() #shows fonts available in R. 
worked.

This is good.

script:

library(extrafont)
font_import(pattern = "[X/x]kcd", prompt=FALSE)
fonts() #shows fonts available in R. 

font_import() #imports lots of fonts including those below. 

# Type font examples
plot(1:10,1:10,type="n")
text(3,3,"Hello World Default")
text(4,4,family="Arial Black","Hello World from Arial Black")
text(5,5,family="xkcd","Hello World from xkcd")
text(6,6,family="Times New Roman","Hello World from Times New Roman")

Gives this output:
