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),s...

Re: diamond graphs, patents and rootograms
...as a background. Does change happen
from the tool or the user.
So I guess my reason for saying R will make more of an impact is because
the average R user cares about what they are doing when compared to the
average Excel user.

Now I can't work out what the wink means, but they're implemented in the
VCD package

how to plot chi-square distribution in the graph
if i want to plot the chi-square distribution with a different degree of
freedom how can i plot it in the graph?Sometimes i plot the histogram and
cut it in a lot of piece.It's distribution like a chi-square.So i want to
plot the chi-square with a different degree of freedom to compare it .

Violin plot for discrete variables.
Dear Rgurus,
To my knowledge the best way to visualize the distribution of a discrete
variable X is
plot(table(X))
The problem which I have is the following. I have to discrete variables
X and Y which distribution I would like to compare. To overlay the
distribution of Y with lines(table(Y)) gives not satisfying results.
This is the same in case of using density or histogram.
Hence, I am

declaring package dependencies
I received the following email note re: the vcdExtra package

But, I can't see what to do to avoid this, nor understand what has
changed in R devel.
Sure enough, CRAN now reports errors in

new package "vcd" 0.1-3
...mples from the book
"Visualizing Categorical Data" by Michael Friendly. By now the features
of the package essentially cover chapters 2-4 from the book:
o fitting and graphing discrete distributions:
goodness-of-fit tests for poisson, binomial and negative binomial
distribution; rootograms; Ord plots; poissonness plots.
o 2-way contingency tables:
improved fourfold displays (compared to base); trilinear plots;
sieve diagrams, agreement charts.

Labels on axes with log scales with lattice
I using lattice to make some plots and I want to make the y-axis on
some of these plots use a log scale. In the following plot:
x <- 1:10
y <- 2^x
xyplot(log10(y) ~ x)
I get tick marks on the y-axis at 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0. I
would rather have just 3 tick marks at 1.0, 2.0, and 3.0 but labeled
10, 100, and 1000.
I know this can be done using the "at" and
