R help - Nov 2012 - How to make pch symbols thicker?

Hi I need to know how to make pch symbols like pch=3 (+) or pch=4(x) or even
the border of squares or triangles thicker without changing the size. I have
a lot of symbols of different colors but you can't see the colors clearly
and I don't want to change the symbol.
Thanks!

Hi,

Have you tried the lwd= argument?  Like this...

plot(1:10, pch = 3, lwd = 4)

Cheers,
