Right, so why do you think it accepts `ylab'? There seems to be a crop of
people asking questions or sending bug reports who think `xlab' and `ylab'
are graphical parameters, but that are actually arguments to title() which
plot.default passes through.
What you can do is call title(), as in
library(MASS)
truehist(rnorm(100))
title(ylab="some y label")
