Hello,
I think the histograms may have been unintentionally omitted from the

get the histograms instead of the density plot:

I think you have to visit the following website to get information about java
packages:
http://www.rforge.net/rJava/ http://www.rforge.net/rJava/
Then of course the official R documentation which describes how to build
packages for R.

It might be easier to move to a higher order plotting model, like
ggplot2 or lattice.
For a similar plot in ggplot2, all you would do is:

you would need to do some tweaking to get the plot exactly like you

Hi Folks,
I'm using the 'norm' package (based on Shafer's NORM)

Here are three successive examples of simple quadratic programming problems
