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?
Thank you for your help,
Jonathan

>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')
