Brad,
can you, please, let us know what is the "bug" here? If you paint semi-
transparent line over the same filled shape (same vertices), clearly
half of the line will be inside and and half outside of the shape, so
each part will have a different color - that is the whole point of
semi-transparency. Therefore I fail to see any bug or unexpected
behavior here.
Cheers,
Simon

Problem : When drawing transperant points with lines thick-
lines(lwd>1) + fill
(pch=21-25), it looks like the line is transperantly overlayed over
the fill,
making it look like 2-lines surround the fill (each a different
color). I
actually think that this is a nice OPTIONAL way to draw the points
(even as
default), but since I could not discover how to turn it off, I
decided to issue
the ticket. In this option can see on the default-quartz device as
well as
PDF-device.
Solution : Have the entire point-object designed/drawn as if there is
no-transparency, then make the composite object transparent.
Optionally figure
out an option to determine whether to apply transperancy as a group
(to the
entire object) or separately (as it is now).
Code :
df <- data.frame(X=rnorm(50),Y=rnorm(50))
plot
(X
~
Y
,data
=df,pch=c(21,22,23,24,25),cex=5,col="#00FF0055",bg="#FF000055",lwd=6)
Thanks,
-Brad Vance
