Dear All,
   
  I am looking for the best way to use graphs from R (like xyplot, curve ...)   for a presentation with powerpoint. I used to save my plot as pdf and after to copy them as image in powerpoint but the quality is not optimal by so doing.
   
  Another completely independent question is the following: when I use "main"  in the  xyplot, the main title is very close to my plot, i.e. no ligne separate the main and the plot. I would like my title to be well distinguished from the plots.
   
  I would be grateful for any improvements...
   
  Many thanks,
   
  Bernard,
