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

...Is it possible to make the unicode string function when writing to a pdf or do I need to form the sigma symbol some other way?

I'm trying to annotate a density plot and I would like to have R calculate the standard deviation and place it in the plot next to the standard deviation symbol "sigma". I can successfully use the text command to paste "StDev =",round(sd(Data),digits=3)) on the plot. However, I have trouble when I want to replace "StDev" with the Greek symbol sigma (See code
