Re: [Rd] alpha transparency doesn't work for lines when xpd=TRUE

2018-04-16 Thread William Dunlap via R-devel
The problem occurs in the Windows GUI with the 'windows()' graphics device. In the following example the red diagonal line appears in 3 plots but not in the one with xpd=TRUE and alpha.f=0.9. > par(mfrow=c(2,2)) > for(xpd in c(FALSE, TRUE)) for(alpha.f in c(.9, 1))

[Rd] alpha transparency doesn't work for lines when xpd=TRUE

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
