I've now uploaded various "com" ¡­

I've now uploaded various "com" files with R scripts. Check them, try them out [using e.g. `source ("com43a")'], perhaps with some variations, to get acquainted with R scripts and their uses, including matters of plotting curves etc.

com files uploaded now include those used by Nils for numerical work associated with Exercises 2.8, 2.10, 2.11, 3.11, and the Nils extra one with Dirichlet analysis of multinomial data.
