[R-sig-teaching] adding plus/minus 1 standard devaition into each bar in cluster bar chart

[Ian Fellows]

Superior plots can be made pretty easily in ggplot2
library(ggplot2)
ggplot() +
	stat_boxplot(aes(y = mpg,x = factor(gear)),data=mtcars,width = 0.5) +
	geom_point(aes(x = factor(gear),y = mpg),data=mtcars,position = position_jitter(height = 0.0,width = 0.1))

There is also a convinience function in Deducer that does much the same thing:

library(Deducer)
data(mtcars)
oneway.plot(formula=mpg~gear,data=mtcars,alpha=1) #with one variable
oneway.plot(formula=d(mpg,disp,hp,drat)~gear,data=mtcars, alpha=1) #with multiple variables
