Consider the following surface (just for fun, in order to illustrate the idea) > f=function(x,y) x*y+(1-x)*(1-y) > u=v=seq(0,1,length=21) > v=seq(0,1,length=11) > f=outer(u,v,f) > persp(u,v,f,theta=angle,phi=10,box=TRUE, +...

My Commonly Done ggplot2 graphs

In my last post, I discussed how ggplot2 is not always the answer to the question “How should I plot this” and that base graphics were still very useful. Why Do I use ggplot2 then? The overall question still remains: why (do I) use ggplot2? ggplot2 vs lattice For one, ggplot2 replaced the lattice package
