Hello,
I would like to create a plot composed of stacked boxes (squares or
rectangles), where the size of the box would represent the frequency
of
observations based on a categorical variable (group), the color would
represent the proportion of success (binary) within that group
(outcome) on
a predetermined color scale. Ideally the boxes can be stacked from the
bottom left to the top right based on size. The x and y scales are not
informative. I am experimenting with the rect() function and loops
but I
wasn't able to generate an appealing graph.
Thanks
Osman
Here is simulated data set
group<-rep(c('a','b','c','d','e','f','g'),c(100,20,300,40,2,10,40))
outcome<-c(sample(c(0,1),100,rep=T,p=c(0.98,0.02)),
sample(c(0,1),20,rep=T,p=c(0.9,0.1)),
sample(c(0,1),300,rep=T,p=c(0.99,0.01)),
sample(c(0,1),40,rep=T,p=c(0.95,0.05)),
sample(c(0,1),2,rep=T,p=c(0.5,0.5)),
sample(c(0,1),10,rep=T,p=c(0.9,0.1)),
sample(c(0,1),40,rep=T,p=c(0.8,0.2)))
df<-data.frame(group=group,outcome=as.numeric(outcome))
