BDR's TODO list

This page contains my plans for enhancements to R. Remember R comes with absolutely no warranty, and that applies to this site and this page in particular.

For R version 1.0

• Sort out the external API, that is what is defined in S.h and similar files, and how to access the random number generators, and so on.
• Replace arima0 by better internal code and a better interface.
• A comprehensive suite of optimization routines, probably callable as methods from nlm.
• A bitmap graphics device, covering at least png, bmp and jpeg on UNIX, as we have on Windows already. This will at least partially replace dev2bitmap.
• A cleaner approach to `files' and URLs. Possibly something along the lines of S4's connections.

Longer term

• The ability to write WMF on Unix (but it looks as if we know too little to achieve this).
• Something better than gam for additive models. Perhaps along the lines of BRUTO (in package mda).
• More time-series models, e.g. Harvey's structural models.
