tsModelSpec pre-release 0.2

I'm making available a pre-release of the tsModelSpec package for R.  This package has some simple modeling functions that are useful for time series models of air pollution and health.  Right now there's only a source package and it is available here.

tsModelSpec

I'm also working on a package called tsModelSpec which is supposedly for time series models of air pollution and health data. The package is very preliminary right now and won't be releasing anything soon. Part of the goal is to design some classes (probably S3 because they inherit from other S3 classes) and methods for time series regression models.
