Dear all:
Is there a way to add text to the margins or outer margins of a mosaic plot
using the vcd package? I understand the margins argument to mosaic, but I
don't know how to add text to that.
I'd like to add a caption to a plot. If possible, I'd like to know how
to set the font and size for that function as well. My plot looks roughly as
below.
Thank you for your time!

mydat<-data.frame(gender=factor(rbinom(100, 1, 0.5),
labels=c('female', 'male')), hair=factor(rbinom(100, 1, 0.5),
labels=c('blonde', 'black')))
mosaic_1<-table(mydat)
mosaic(mosaic_1, gp=shading_hsv, main='my title', pop=FALSE,
split_vertical=FALSE, margins=c(4.1, 2.1, 8, 5.1),
labeling_args=list(rot_labels=c(left=0), offset_labels=c(left=3),
gp_main=gpar(cex=2), offset_varnames=c(left=5.5), gp_labels=gpar(cex=1.5),
gp_varnames=gpar(cex=1.5), labeling_values=c('observed')))
labeling_cells(text=round(prop.table(mosaic_1, 1)*100), gp_text=gpar(ces=2),
clip=FALSE)(mosaic_1)
