[R] fontsize in mosaic plot lables

[Alexander.Herr at csiro.au]

Thanks Patric,

mosaic{vdc} takes gpar parameters. So cex.axis does not work for 

mosaic(Titanic, pop=FALSE,
labeling_args=list(rot_labels=c(bottom=90,top=90),cex.axis=0.5)) 
or
mosaic(Titanic, pop=FALSE,
labeling_args=list(rot_labels=c(bottom=90,top=90)),cex.axis=0.5)

However,
mosaic(Titanic, pop=FALSE,
labeling_args=list(rot_labels=c(bottom=90,top=90),gp_labels=(gpar(fontsi
ze=5))))

works for all labels.

Is there a way to adjust only one set of axis labels?

Thanx and cheers
Herry

The mosaic function isn't part of lattice.  Try cex.axis in a more or
less normal way instead of gpar settings.
