I'd like to announce the availability of the "tsne" package.

It provides the T distributed Stocastic Neighbor Embedding algorithm by van der Maaten and Hinton:

In Proceedings of the Twelfth International Conference    on Artificial Intelligence and Statistics (AISTATS), JMLR W&CP 5:384-391,    2009. [ PDF<http://ict.ewi.tudelft.nl/%7Elvandermaaten/t-SNE_files/Paper.pdf>]

It has a few utility/convenience parameters for tweaking the algorithm and providing feedback. Be sure to try the example to get an idea of how it works:

require(tsne)
?tsne

It's currently much slower than the "official" implementations by van der Maaten. If you're interested in providing some tips on optimized C/Fortan code, let me know.

Best,
-Justin
