Thanks. It must be also true for 2.6.2.

To control appearance of graphics produced for the web.

We are trying to introduce R in our workflow. It is easy to figure out 
why. Currently, Excel, SPSS and several software flavors producing 
graphics and tables are involved. A kind of mess that nevertheless 
works. But I am sure R can substitute each and all  of these tools and 
to add a great deal of advantages. We keep discussions about papers we 
prepare in a wiki system. To produce neat graphics from R to be display 
in wiki pages is a must for me now.

To build my own binaries of several FOSS projects I working with is high 
in my ToDo list! But I will take profit of Simon's work to re-start with 
R now. Thanks to Simon.

Thanks for your help,
