Dear R-package Folk,

I am pleased to announce the release of a new version of the ndl package (

What is NDL? It is a simple learning model based on the Rescorla-Wagner
model of discrimination learning.

I have become the new maintainer, replacing Dr. Antti Arppe (thank you for
all your hard work, Antti!)

This release is a major update. In particular the following items are new
since the last CRAN version (v 0.1.6 from Dec. 2012)

* improved speed in counting co-occurrence counts through the use of Rcpp
and C++ functions.
* improved scalability: it can process many millions of events, with much
larger numbers of cues and outcomes.
* support for Unicode text
* new ability to count background rates (optional)
* new method for converting counts to probabilities
-- and many other small improvements.

For access to the development branch, to join development,  or to submit

Best regards,


Cyrus Shaoul, PhD
