Implementing the CountSummary Procedure

In my last post, I described and demonstrated the CountSummary procedure to be included in the ExploringData package that I am in the process of developing.  This procedure generates a collection of graphical data summaries for a count data sequence, based on the distplot, Ord_plot, and Ord_estimate functions from the vcd package.  The distplot function generates both the Poissonness...

One of the main attractions of R (for me) is the ability to produce high quality graphics that look just the way you want them to. The basic plot functions are generally excellent for exploratory work and for getting to know your data. Most packages have additional functions for appropriate exploratory work or for summarizing
