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?
R graphics only recognizes a plain symbol font (it has this weird idea
that a symbol font is a font face like bold or italic).
For your particular example, because it is not a complex math formula,
you might be able to do a workaround by constructing a simple string and
specifying the symbol that you want using Unicode. Depending on what
system and fonts you have, the following might work ...
text(25000,0.00004,
paste("\u03c2 = ",
format(round(sd(Data),digits=3),big.mark=",")),
font=2, col="blue")

Thank you for your help,

[R] Using bold font with bquote
From ?plotmath, it looks like when using expressions you set the
font
inside the expression (e.g. bold(x)). It looks you tried this already
but I wonder if there was something tiny out of place since the
following works for me:
text(25000,0.00003,bquote(bold(sigma==.(mySigma)),list('mySigma'=format(round(sd(Data),digits=3),big.mark=","))),
col='blue')

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
