Time for a completely reproducible example a la the posting guide.
Plese show us _exactly_ what you did that does not work for you: your
original posting did not have lwd in the example.

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)...

I tested in R versions 1.8.1 and 2, but doesn't

The attached plots can explain this. And mar isn't
a
parameter to postscript command. If I use in par,
it
doesn't affect the outpu.
It does in R-2.0.1!!! Please try out what poeple are
suggesting!
You have to set par() for the current device, so
after your call to
postscript, as I have indicated below.

Hi all.
I'm working with a short plot (3x3 inches), but
the
results (via postscript command) are not nice.
The
lwd
command don't affect the lines (that are very
large)
and the margins don't change using oma, mai, mar,
...
Below I put an example. Moreover, save the
graphics
via postscript command isn't working well (see
the
attached ps).
Thanks by the help,
Setting lwd=0.5 works for me, as well as using
par(mar=c(....))

q<-summary(scores)
gra<-hist(scores, breaks=((0:11)/2-.2),

yy<-ceiling(max(gra$counts)/10)*10

par(mar=rep(1,4)+.1, lwd=0.5)
hist(scores, breaks=((0:11)/2-.2),

add lwd=0.5

boxplot(scores, horizontal=1, add=1,
