[R] Combing xyplot and curve() plot via print

[Greg Snow]

The xyplot function is a lattice function that uses grid graphics.  The curve function is a base graphics function.  'par' and 'layout' work with base graphics, the print idea works with grid graphics.  Grid graphics and base graphics don't mix easily.  One option is to find a grid/lattice/ggplot2 alternative of the curve function so that you are using all grid graphics, or you can use base graphics to recreate the xyplot in base.  There is also the gridBase package that makes combining the 2 systems easier (but still not simple).

Hope this helps,
