[R] Bold Face in Plot

[Greg Snow]

Here is one way:

thestring <- "the-actual-string"
plot(0:1,0:1,type="n")
text(x=0.5, y=0.5, labels=bquote(bold(.(thestring))))

There is an example in the plotmath help page that shows using bquote (but that page has so much information that I did not find it on my first scan through even knowing what to look for).

Hope this helps,
