by output into data frame
...me roughly like this:
subid cortisol.auc amylase.auc
2 919.05 6834.8
3 728.25 24422.05
etc.
What is a nice way to make that happen?
Here is the code and data that I am using, which should run directly if you copy and paste it:
sanity.check<-read.csv("http://brainimaging.waisman.wisc.edu/~perlman/testdata.csv", header=TRUE, sep = ",")
lab.samples <- subset(sanity.check,Sample!='before bed' & Sample!='morning after')
lab.samples$Sample<-factor(lab.samples$Sample)
lab.samples.stress<-subset(lab.samples,challenge=='stres...

There must be a better way to do this
I made this rather cool plot which I am quite pleased with:
http://brainimaging.waisman.wisc.edu/~perlman/data/BeeswarmLinesDemo.pdf
However, I feel there must be a better way to do it than what I did. I'm attaching the code to create it, which downloads the data by http so it should run for you if you have the current version of beeswarm installed (which was just update...

Group labels in lattice barchart
...This seems like a very critical piece of information which, for some reason, is kept well-hidden...
Any help will be greatly appreciated!
The following commands should produce an example plot by pasting directly into R, assuming you have a net connection:
library(lattice)
load(url('http://brainimaging.waisman.wisc.edu/~perlman/testdata.rdata'))
print(barchart(Count~Rating | RateType*Temperature, data=tf, groups=StimCount,
stack=TRUE, scales=list(alternating=c(3)), ylim=c(0,11),
par.settings=list(superpose.polygon=list(col=rainbow(10))),
auto.key = list(points = FALSE, rectangles = TRUE, spa...
