[R] short plots: lwd, margin and postscript behavior

[Mike Saunders]

Don't feel alone Cézar; I have had the same problems getting par commands to 
work when making *.pdf files.  I also run R 2.0.1 and use par() after 
opening the device.  Sometimes, the par() commands work; sometimes it opens 
a new windows device.  Maybe something with MS Windows is causing this.

Thank you so much, but the commands in par doesn't
affect the pictures generated by postscript.
For example, I put lwd=3, and the postscript file is
the same, using par(lwd=3) or par(lwd=.5)...
