Hi,
Try this:
pdf("broke.pdf")
palette(rainbow(6))
plot(x=x1,y=y1,col=y1,xlim=c(-10,20))
palette(heat.colors(6))
points(x=x2,y=y2,col=y2)
dev.off()
A.K.
Yep. Notice though that this is not specific to dev.copy2pdf, the same effect happens if you just resize the the screen device. Seems like palette changes are not recorded in the display list. Not sure whether that is by omission or by design.
I believe it is by design. palette() is part of package grDevices, and you should think of the palette as a per-session setting. (It is stored in R itself, not on the device and not in package grDevices.) So plots are plotted using the last palette set in that R session, including being re-plotted.
