About a year ago, I noticed that the image() function generated fine grid lines in graphics when using the quartz() device but not x11() and that these lines could be found in the pdf() generated images when viewed in some but not all pdf viewers. The link to my original message is here:
https://stat.ethz.ch/pipermail/r-sig-mac/2005-March/001650.html This problem still occurs and was wondering if there was any progress on resolving it. Thank you. Here, again, is some code from the 2005 message that should permit you to see the grid lines. quartz() chkb8 <- matrix(rep(c(rep(c(1,2), 4), rep(c(2,1), 4)), 4), ncol = 8) chkb16 <- kronecker(chkb8, matrix(1, ncol=2, nrow=2)) chkb16[6:11, 6:11] <- 1 chkb16[8:9,8:9] <- 3 image(chkb16, axes=FALSE,col=c("red","green","yellow")) Ken Knoblauch [[alternative text/enriched version deleted]] _______________________________________________ R-SIG-Mac mailing list [email protected] https://stat.ethz.ch/mailman/listinfo/r-sig-mac
