R packages - Sep 2008 - STAR (Spike Train Analysis with R) uploaded on CRAN

Hi all,

I've uploaded STAR (Spike Train Analysis with R) on CRAN two days ago.

The package is designed to analyze neuronal spike (action potential)
trains. It uses S3 classes and methods and makes heavy use of other
CRAN packages like gss, R2HTML, mgcv, survival.

* Analysis of both spontaneous and stimulus evoked activity is
implemented for single neuron spike trains as well as for many neurons
recorded simultaneously.
* Several bi variate duration distribution can be automatically fitted
to "spontaneous" spike trains. Tests for renewal processes are
implemented.
* A non-parametric, smoothing spline based, approach to the estimation
of the conditional intensity of the trains is also available (this
feature is under development).
* The full collection of Ogata's tests (1988, JASA, 83:9) for
point-process models is implemented and the data set used by him
(table 1 of the paper) is made available.
* A new goodness of fit test for point-process is also proposed based
on the fact that the martingale of the process plotted as a function
of the integrated conditional intensity starts behaving very quickly
as a standard Wiener process (if the model is correct). By the way I
have no clean and formal proof of the latter statement so anyone able
(and wiling) to give me some help on that is invited to send me an
email.
* Many data sets are included as well as vignette (covering only part
of the present functionalities) and several demos.

Any feed-back, comment, critic, is welcome.
