[R] bubble plot problems

[Pieter Provoost]

Hi,

I'm having some problems with a bubble plot (ps package). I don't want 
tick marks on all four sides (just two), I want to have a smaller font 
size, and I would like to be able to define bubble sizes shown in the 
legend (now it shows 0, 0, 0, 9.747 and 4265.757 which is not really 
convenient. Passing some of the standard plot arguments didn't help (in 
fact, nothing changed).

bubble(points,fill=FALSE,aspect='fill',main='macrofauna',col='black',scales=list(y=list(tick.number=numberspecies,labels=rev(names(data)))),ylim=c(1:numberspecies))

Thanks,
Piet
