Thank you, Bill, for your reports ("lwd" and "lty").
In the future, would you please indicate exactly which version of R you are
using?

"lwd":  in 0.61.x, it only works for x11/X11, not for postscript.
	in 0.62.x  it should work in all cases, also in combination with lty.

 lty :  Could n't your problem of seeing just one kind of dot-dashes
	be a problem of screen / device resolution alone?

Thanks again for these bug reports; at the moment we are interested
increasingly more and more for report about 0.62. But even there
-- since we are now in a "fixing" mode -- you have to indicate the version
  (date) that you are using.

I am using
[1] "Unstable-snapshot"

$status.rev
[1] "0"

$major
[1] "0"

$minor
[1] "62.0"

$year
[1] "1998"

$month
[1] "April"

$day
[1] "12"

If I do:
plot(x,y, type="l")
par(lwd=4)
lines(tt,pts)

The 2nd curve does appear to be heavy (correct line width) in X11 window,
however saved plot (dev.print) uses just single pixel line width (as seen
when viewed in ghostview or when printed out).

So if lwd is supposed to work in version .62.0, then there is a bug.
Or else I need a newer snapshot.

As for lty, this was just a confusion of lty="2" and lty=2, etc, as
Peter said.  Yes as you say Martin the screen resolution does enter into
it, but I was basing my comments on printouts.

This certainly seems as though it has great potential for confusion!
I don't know if there is any feasible change to the plot command itself to
minimize this confusion, but may I ask (maybe someone has already done it)
that a few lines be added to the documentation ... ?
