Hi
I can't use box() as I don't want to draw a box round my entire plot, I just want to draw a box as the background to certain subsets of the bars.
One idea. Edit the barplot.default function so it doesnt call plot.new.
do:
myBarplot = barplot.default
then edit the myBarplot function. Add an extra parameter to the argument list 'add', and make it False by default:
cex.names = par("cex.axis"), inside = TRUE, plot = TRUE,
axis.lty = 0, add=F, ...)then find plot.new and wrap it in a condition:
if(!add)plot.new()
Now try:
tN <- table(Ni <- rpois(100, lambda=5)) myBarplot(tN) rect(2,1,6.5,8.5)
- this puts the rectangle on top of the bars, which you dont want, so you call myBarplot with add=T so that plot.new isnt called and the barplot appears over the rectangle:
myBarplot(tN,add=T)
works for me, if I understand your problem correctly!
