Part of the reason I was having difficulty is that I'm trying to add a
legend with more than one element:
plot(1,1)
obv = 5
txt = "Pop mean"
# this works
legend("topleft", legend=bquote(.(txt) == .(obv)*degree))
# but this doesn't
legend("topleft", legend=c(bquote(.(txt) == .(obv)*degree), "Von Mises
distribution"))
How can I go about using multiple legend elements with mathematical/latin
annotation in both?
