Hello R experts,
 I am trying to use hmap from package seriation or bertinplot.
I have two questions:
How can I specify smaller font? I tried with
pushViewport(viewport(layout=grid.layout(nrow = 1, ncol = 2),
+ gp = gpar(fontsize = 8)))
but didn't work for the font with bertinplot.

Also for hmap I need to arrange the margin so that all the labels are
visible.
I tried with par(mai=c(3,2,2,2)), but also with no luck.
Any help will be really great.
Thanks a lot,
Mitra.
