[R] Barplot not showing all labels

[William Dunlap]

If the problem is that not all y-axis labels fit on the horizontal barplot
with the default settings, you can rotate then to horizontal with las=1
and reduce their size with cex.names=0.5 to avoid overlap, as in
   barplot(structure(1:50, names=state.name), horiz=TRUE,las=1, cex.names=0.5)
or, using plotrix::staxlab, as Jim Lemon suggested, to spread them out
in alternating columns
   staxlab(2,at=barpos,labels=URLcodes[noUS],nlines=2,las=1,cex=0.5)
