[R-SIG-Mac] Graphics plotting options

[John Chambers]

There is an extended version of John Tull's question that initially 
looks harder:  "How to do the same thing with lattice (or grid) graphics?"

par(ask=TRUE)

doesn't have any effect on example(xyplot), for instance.  (And since 
lattice uses grid graphics, there's no reason it should.)

The answer in this case is to use the call:

grid.prompt(TRUE)

and one further complication is that grid.prompt() is not visible to the 
user if you just require(lattice), presumably because the lattice 
namespace doesn't export this function.  To get the functionality, you 
need to explicitly do:

require(grid)

after which the grid.prompt() works fine and has the desired result.

(I suspect this is not really a Mac OS X question, but haven't tried it 
on Linux, e.g.)
