Subject: [Rd] alpha transparency doesn't work for lines when xpd=TRUE
Message-ID: <BBFFC8D403F0364E9A4176D542D830E912BF842A@SRV12-0032.cri.camres.org>

Dear R-devel,

I think I've found a bug - the alpha transparency doesn't work when plotting lines with xpd = TRUE.

#works
plot(1:20, col="#1874CD", xpd=T, type="l")

#works
plot(1:20, col="#1874CD50", xpd=F, type="l")

#doesn't work
plot(1:20, col="#1874CD50", xpd=T, type="l")

Thank you.

Jim
