[R-lang] wonky PDF labelling behavior in R

[Harry J Tily]

Hi Paula

I think the problem is that hist() is itself a plotting command -- you
don't need to wrap it in plot() at all. It turns out that hist *also*
returns a histogram object which you can then plot with plot(), so when
you do that the X display immediately replaces the figure created by
hist() with the one created by plot()... but the pdf device saves the
first figure, the one created directly by hist().

Try passing the graphical parameters (xlab, etc) directly to hist(), or
use plot=F as a parameter to hist() if you want to use plot() to do the
rendering.
