Hi, as Prof Ripley points out, standard R graphics concepts might not work with grid/lattice. In particular, use of the par() function is not guaranteed to give desired results. Another feature of Trellis (hence lattice) graphics is that the paradigm of adding bits and pieces to an existing plot don't work. For your particular example, it would be helpful to know what you are attempting to do. Superimposing two plots (which is what it seems you are trying to do) might be a bad idea. If you want to put more than one plot on the same page, try print.trellis() with more=T, along with either position= or split=. (See the help page for print.trellis for details and examples.) [Remember to start the postscript device by trellis.device() and not postscript().]

Hi, I was using xyplot and find problems in printing (on a postscript file) when there was a session like xyplot(....) par(new=T) xyplot(....) basically the result is the ps contain only he last xyplot! any obvious things to do? thanks Didier -- Didier G.
