[R] several plots on several pages

[Greg Snow]

You can set up the 3 plots per page by using:

> par(mfrow=c(3,1))

Then there are a couple of options for skipping the top graphics
position if the graph fails.  If you know that the graph failed then you
can just use plot.new() (or frame()) to skip the top plot and plot the
next one in the 2nd position.

Another option is you can call par(mfg=c(2,1)) explicitly before
plotting the 2nd plot to force it to plot in the 2,1 position.

Hope this helps,
