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.
Yours, Simon Kiss

Varying
the chroma and the luminance only affect the distinctions between
large

negative residuals are both large (absolutely) and significant,

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
"-".
