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
Using bold font with bquote
2 messages · Jonathan R. Blaufuss, Scott Sherrill-Mix
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')
