Own classes in "histogram"
Hi,
I try to make a histogram from a variable that contains the number of
shoots from about 1000 individuals from a specific plant species (the range is 1-110).
Those numbers are highly skewed to the right.
My question is: how can I make my own classes with the lattice
"histogram"?
I tried it with "breaks=c(0,5,10,15,20,25,110)" but my "25-110"-class is presented

rootogram for normal distributions
Using R-2.12.1 and latticeExtra-0.6-14, I would like to understand
why a rootogram displaying samples from the Poisson distribution looks like I
expected it, whereas a rootogram using the normal distribution does not:
library(latticeExtra)
rootogram(~rpois(1000, lambda = 50), dfun = function(x) dpois(x, lambda = 50))
rootogram(~rnorm(1000), dfun = function(x) dnorm(x,mean(x),sd(x)))
