helpeRs, I have a nice looking mosaic plot in an article to be published soon. Sadly, the published version will be in black and white and so ruin the advantage of the default shading scheme of tiles.
What would readers suggest as an alternative shading scheme? If I have a black-and-white shading scheme graduated according to suitable cutoffs I won't be able to tell positive from negative residuals. The tile borders can be changed of course, but I'm uncertain that is will be clear enough for a reader. Another option may be to use a fill pattern of sloping lines with different orientations for the sign and density for the magnitude. The problem with this option is I wouldn't know where to start to incorporate into a legend. The shading_binary function is no good as I would like the cells with residuals less than absolute 2 to be different from other cells. How would readers of this list represent a mosaic plot so that it was easily interpretable in monochrome? My data can be used as an example: library(vcd) library(MASS) term.1 <- gl(2,1,8, labels = LETTERS[1:2]) term.2 <- gl(2,2,8, labels = LETTERS[3:4]) term.3 <- gl(2,4,8, labels = LETTERS[5:6]) cell.count <- c(72, 19, 5, 8, 117, 115, 81, 85) mosaic(loglm(formula = cell.count ~ term.1 + term.2 + term.3), shade = TRUE, gp = shading_hcl, legend = TRUE, labeling_args = list(rot_labels = rep(0,4)), gp_args = list(lty = 1:2),legend_width = unit(0.2, "npc")) ------------------------------------------------------------ Dr Michael Townsley Senior Research Fellow Jill Dando Institute of Crime Science University College London Second Floor, Brook House London, WC1E 7HN Phone: 020 7679 0820 Fax: 020 7679 0828 Email: [EMAIL PROTECTED] ______________________________________________ R-help@stat.math.ethz.ch mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
