[R] geom_histogram help

[John Kane]

Without your code it is impossible to say why you are getting the error message.  

However, are you aware that you need to have a classifying variable to set the colours?  

Try this to see if it is something like what you want.
======================================================================
library(ggplot2)
dd  <- rnorm(100, 5, 2)
cuts <- cut(dd, breaks =c(3,5,7))
mydata=data.frame(dd,cuts)
p=qplot(dd, data=mydata, geom_histogram="histogram", fill = cuts)
p
