[R] Padding in lattice plots

[Federico Gherardini]

Hi all,
I've used the split argument to print four lattice plots on a single page. The 
problem now is that I need to reduce the amount of white space between the 
plots. I've read other mails in this list about the new trellis parameters 
layout.heights and layout.widhts but I haven't been able to use them 
properly. I've tried to input values between 0 and 1 as the padding value 
(both left and right and top and bottom) but nothing changed. It seems I can 
only increase the padding by using values > 1. Any ideas?

Thanks in advance for your help
