Changing Fonts for Graphs in R

Question

In my study I am generating various graphs using R. I see that most of the graphs come up with a Sans Serif type font with various sizes.

How to I change all the te

Answer 1

You can change the font in Windows to Times New Roman using the windowsFonts() command and the family option in plot:

x = seq(1,10,1)
y = 1.5*x
windowsFonts(A = windowsFont("Times New Roman"))
plot(x, y,
  family="A",
  main = "title",
  font=2)

Bold text comes from font=2. As for the size, see ?cex(). Also, see here: http://www.statmethods.net/advgraphs/parameters.html
