Thank you for helping,
Actually, lwd=.5 in plot() or par() brings neither error nor warning message, but lwd below 1 seems not to be taken into account, as plot(..., lwd=1) and plot(..., lwd=.5) look quite the same.
On what device: see below?
Besides, it is mentioned in the lwd section of the par() help page : " (...) some devices do not implement line widths less than one".
(The people who write the documentation do tend to know what it says:
you omitted `The interpretation is device-specific' and it seems did not look in the device-specific documentation.)
This _is_ documented under both ?postscript and ?pdf as
Line widths as controlled by 'par(lwd=)' are in multiples of
1/96inch. Multiples less than 1 are allowed. 'pch="."' with 'cex
= 1' corresponds to a square of side 1/72 inch.You haven't mentioned the device (or version of R) you are using, nor the commands used nor how you are viewing the output.
I checked the sources: the quartz() device is restricted to lwd >= 1, so this might have resulted from plotting on that and then copying the plot.
What I am looking for is how to get readable plots (with not too wide lines) after size reduction...
Using postscript() or pdf() directly works for me, and the code is the same on all R platforms.

Someone, who uses R under Mac, wants to insert a couple of small plots (each with several lines) in an article, but he has to reduce plots' size significantly. He did it (in pdf or enc. ps) but, unfortunately, everything is reduced but lines' width. Besides, 'lwd' argument in par() or plot() can't be less than one.
IANAMU (I am not a Mac user) either, but you should definitely be able to set lwd to less than 1. What happens when you try par(lwd=.5) or plot(1:10, type="l", lwd=.5)?
I am not a Mac user and I don't know whether it is a Mac-related problem or not.
Could somebody please give me a way to solve this problem, either to reduce line width under R, or to get reduced lines' width when reducing plot size ?
