Sundar,
Thanks. Unfortunately, I am looking for something that also works in the margins of the plot.
As a workaround, what about frac() (well, vertical justification is not that perfect in this case)?
plot(1:10, xlab = "")
title(xlab = expression(frac(y == X * beta + e)),
line = 4.5)I'll probably take a look how to add that feature during August.

Hello All,
Is there an analogue to \underbar or the AMS math \underline in graphical math expressions?
Thanks,
John.
Uwe Ligges posted a solution a couple of years ago. I don't know if there is anything built in yet. ?plotmath does not seem to say anything about underlining.

plot(0:1, 0:1, type="n") underlined(0.5, 0.5, expression(widehat(x %*% y)))
