I'm trying to annotate a density plot and I'm using bquote to paste the
sigma symbol next
to the numeric text of the standard deviation calculation that I am performing.
I have been able to successfully turn the sigma symbol and numeric output the
color blue,
but when I try to change the font of the text to bold, R doesn't seem to
recognize the "font="
command in the same way here as it does with "col=". (My code is
below)
set.seed(1)
Data=rnorm(100,sd=10000)
plot(density(Data))
text(25000,0.00003,
bquote(sigma==.(mySigma),
list('mySigma'=format(round(sd(Data),digits=3),big.mark=","))),
col="blue")
After searching the help files I've tried using the expression command with
"bold()" as well
as inserting "font=2" after the color command. However, I can't
seem to get it to work.
Can someone please point me to a resource that will help me figure this out?
Thank You,
Jonathan

Scott, Your suggestion works great for changing the numbers to bold font, but is it possible to change the sigma symbol and the equals sign to bold font as well? I've poked around ?plotmath and am I right in saying that there is a different method for controlling symbol fonts?
