lty

Sorry, my previous message said using lty="2" made line disappear.  Wrong.

What happens is that
"2" is dots
"3" is dashes

BUT docs say
"2" is dashes
"3" is dots

So there is an error in the docs.

Nope:
	lty=1 solid
	lty=2 dashed
	lty=3 dotted
	lty=4 dotdashed
	lty="1" pattern: 1 "dot" on, 1 "dot" off
	lty="2" pattern: 2 "dots" on, 2 "dots" off
	lty="3" pattern: 3 "dots" on, 3 "dots" off
	lty="32" pattern: 3 "dots" on, 2 "dots" off
	lty="124" pattern: 1 on, 2 off, 4 on, 1 off, 2 on, 4 off, 
	...and so forth...

Peter, to me (and this is English language) "dot" is shorter than "dash"!
.-.--
dot dash dot dash dash.

So "dot" SHOULD be label for lty="2" pattern: 2 "dots" on, 2 "dots" off
And "dash" SHOULD be label for lty="3" pattern: 3 "dots" on, 3 "dots" off.
Since dot is shorter than dash.

You can see this clearly if you start with par(lwd=5). As far as I can
see without actually digging into the source,

This is answer to previous posting on lwd.  So it is there, just not
documented. Thanks.

The dot-dash pattern on X11 looks wrong, though. I think it should
have been "1343", i.e. same pattern, reverse colors.

My comments above were based on viewing saved plot with ghostview and
actually printing it with ghostscript.
