[R] lwd less than 1

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.

Besides, it is mentioned in the lwd section of the par() help page :
" (...) some devices do not implement line widths less than one".

What I am looking for is how to get readable plots (with not too wide 
lines) after size reduction...

Best regards,

Jacques VESLOT
