[R] layout function for several plots

[Greg Snow]

Using ann=F just tells R not to put anything in the margins, it does not reduce the size of the margins.  You need to reduce the margin size using par(mar= ...) with appropriate values.  You can then shrink what goes in the margins rather than not plotting it at all (though that is a good first step to make sure everything else works).

For adding the cross, look at the cnvrt.coords function in the TeachingDemos package, will that do what you want? (look at the examples)

Hope this helps,
