[RkWard-devel] Scatterplot Matrix

[I. Soumpasis]

Hi!

I made one more chart that I had in mind.

It is a scatterplot matrix that can be used with matrices or dataframes, or
with variables from a dataframe or matrix. The function is
scatterplot.matrix from package car. It combines a scatterplot with
"density", "boxplot", "histogram", "oned", "qqplot" or no plot at the
diagonal panel. It can be used for a full picture of data, as correlation
graph.

The user can choose which graph to produce, if he wants points to be ploted,
smooth, or ellipses at the 0.5 and 0.9 (normal) probability or confidence
levels.

I hope there are no problems in this graph and I learned from the previous
one.

Any suggestions appreciated. I hope you like it.

If there are all ok with this graph, I would like to write the help pages
for these two graphs. So what should I do? Write rkh pages? A little
guidance would be appreciated.

Regards
Ilias
