Dear Colleagues,
Thanks for that JIm, but It strikes me that printing the residual values in
the cells might be a simpler way of communicating the direction of each cell.
I can get the residuals printed via the labeling_values commands in mosaic,
but I cannot seem to *combine* this with labeling_borders commands that I'd
like to use to modify the rotation, font size and contents of variable names
and labels.
The following mosaic command draws the plot with the labeling I'd like.
mosaic(~social_class+ctax_agg_scaled, pop=FALSE, shade=TRUE, main="The
Liberals Carbon Tax Or Green Shift Would Hurt The Canadian Economy By EGP
Class Category", main_gp=gpar(fontsize=16), gp=shading_hcl(CST21$observed,
CST21$expected, ASR21, df=12, h=c(260,0), c=c(100,0), l=c(90,50),
interpolate=c(1,2,3,4)), labeling_args=list(labels=TRUE,
rot_labels=c(25,0,0,25), gp_labels=gpar(fontsize=7), just_labels="center",
offset_labels=c(1,0,0,4), offset_varnames=c(2,0,0,4),
set_varnames=c(ctax_agg_scaled="The Liberal Green Shift Or Carbon Tax Would
Hurt The Canadian Economy", social_class="EGP Class Category")))
And when I take out the labeling_borders commands and insert the following,
labeling=labeling_values(value_type=c("residuals"), suppress=0)
then I do get the residuals printed, but the labels are unattractive.
How do I combine labeling_borders and labeling_values commands in one
command.
labeling_values() is a combination of labeling_borders() plus
labeling_cells(). If you want finer control over what happens, I recommend
to use labeling_borderes() in your mosaic() call and then call
labeling_cells() manually afterwards. There is an example on how to do
this in Section 4.2 of the strucplot vignette:
vignette("strucplot", package = "vcd")

how do I set the h,c, and l values such that the significant, positive
residuals appear different on a grayscale printer from significant

distinguish the positive and negative residuals with the hue/. Varying
the chroma and the luminance only affect the distinctions between large
and small and significant and non significant. But my positive and
negative residuals are both large (absolutely) and significant, meaning
that they will have the same chroma and luminosity, but different hues.
I guess the key here is to find two separate hue values that appear
substantially different *on a grayscale printer* at the same chroma and
luminance. I have read through Zeileis et al. (2007, 2008) but can't
quite find the answer there.
I have also tried the Friendly shading to vary the line type, but I
can't find line types that are different enough to communicate the
difference between positive and negative residuals clearly.
Your assistance is appreciated.

Hi Simon,
I thought that the symbolbox function might do something useful, but it
required a bit of modification. The attached mod allows the user to fill a
rectangle with symbols, which includes things like "+" and "-".
