Hi,
I would like to add a dash (—) on a letter in R.
How can I add a dash on letter P in the following:
mtext(text=expression(Winter(DJF)~mean~daily~precipitation~italic(P)), side=3, line=1,
cex=1.3, col="black")
?plotmath could not provide an answer to my problem.
But it refers to demo(plotmath), and that's where you could find the
answer to your question: use bar(). For example,
mtext(text=expression(Winter(DJF)~mean~daily~precipitation~bar(italic(P))), side=3,
line=1, cex=1.3, col="black")
