Hi, the NEWS for R 2.4.0 has: o hist(*, plot = FALSE) now warns about unused arguments. I'm sure this does some good for someone somewhere, but it causes lattice::histogram() calls to produce warnings now in certain cases, which I need to fix. However, ?hist makes no mention of this new state of affairs, and the definition of ``unused'' seems arbitrary since 'freq' and 'probability', which have no effect (unless they contradict each other) do not trigger the warning. Could the help page be clarified to reflect the intent so that I don't get caught by more changes later? Thanks, Deepayan P.S. The help page also has ...: further graphical parameters passed to 'plot.histogram' and their to 'title' and 'axis' (if 'plot=TRUE'). which is grammatically incorrect (I'm not sure what was intended).
