There is a great new book called 'Principles of Computational Modelling in Neuroscience' which has some examples in R; in particular in chapter 10 you will find code for 'Hinton plots' (also known as Willshaw Plots). http://www.compneuroprinciples.org/code-examples/10 Stephen ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
