In R, how to get powers of ten in bold font in a plot label?
- by wfoolhill
I want to have "10^4 points" in bold as my x-axis label.
I know how to make a simple label in bold:
plot(1:10, xlab="")
mtext(text="10 points", side=1, font=2, line=3)
Thanks to this answer, I know how to make a label with a power of ten but nothing is in bold:
mtext(text=expression(paste(10^4, " points")), side=1, font=2, line=3)
Thanks to this answer, I also know how to make a label with a Greek letter in bold:
mtext(text=expression(bold(paste(beta, "=", 10^1, " points"))), side=1, line=3)
But still the power of ten is not in bold!
It doesn't work either with bquote:
mtext(text=bquote(bold(10^1~points)), side=1, line=3)
Any idea?
Here are some details about my system. Let me know if you need anything else.
