Categorical bubble plot

So I have been playing with bubble plot and I was able to create bubble
plot with relatively simple data. I am no having problems when I
increase the complexity of my data. Below is a example of my data:
phytochemical MainClass FitValues
Name A 0.5
A 0.7
A 0.8
B 0.1
B 0.4
B 0.6
Phytochemical in on the y-axis and MainClass on the x-axis and FitValues
is the color and size of the bubble so each x-y has more than one
FitValue. Will the following still Work?
bubble = ggplot2.ggplot(dataf) + \
ggplot2.aes_string(x='mainclass', y='phytochemcial',
col='fitvalue',size='fitvalue') + \
ggplot2.geom_point()
This is done in rpy2 so it may not look like R.
I would expect so, although having the bubbles overlaid on each other may make it hard to see the results clearly. Did you try it and see what happens? In general it is better if you can provide us with full/reproducible examples so we don't have to speculate. You might want to set the points partly transparent (e.g. ggplot2.geom_point(alpha=0.5)). However, at this point I would also consider changing the way you are plotting the data. As I may have said previously (or may have been tempted but kept my mouth shut), colour and size are at the bottom of the "Cleveland hierarchy" -- that is, it's very hard to to reliably interpret quantitative information on the basis of size and colour. A dot chart of some form would probably convey the information more accurately. Ben Bolker

Hi Jurgens,
In the following post I show how to use balloonplot from qplots
to do more or less what you ask:
http://www.r-statistics.com/2010/02/nutritional-supplements-efficacy-score-graphing-plots-of-current-studies-results-using-r/
p.s: the code has a slight modification to it, so to handle
overlapping texts. Dear Jim, I'd be happy if some of it might
be considered into the official release.
Cheers,
Tal

yes -- but you can make one up if you like. e.g.
dd <- expand.grid(drugclass=LETTERS[1:5],
plant=c("cactus","sequoia","mistletoe"))
set.seed(101)
dd$fitvalue <- runif(nrow(dd))
library(ggplot2)
ggplot(dd,aes(x=drugclass,y=plant,colour=fitvalue,size=fitvalue))+
geom_point()
By the way, I think you could represent your data much more
clearly this way: the "Cleveland hierarchy" says that it's
easier
to assess quantitative values plotted along a common scale
than via
size or colour ...
ggplot(dd,aes(x=drugclass,y=fitvalue,colour=plant))+
geom_point()+geom_line(aes(group=plant))
> The size of the bubbles will be related to the fitvalues.
