R help - Oct 2010 - estimate intrinsic dimension

Does anyone know of any packages or have any loose code for estimating the
intrinsic dimension of a data set?

Thanks for any leads,

Jack

Someone said that I need to define "intrinsic dimensionality" in my
question.
Basically, this is the topological dimension of a set of points that are
represented in a space of possibly higher dimension. For example, your data
might describe a corkscrew line through a 30-dimensional space (you measured
30 variables), so the intrinsic dimension of your set of points is 1.

A reference is Trunk, 1976, Statistical Estimation of the Intrinsic
Dimensionality of a Noisy Signal Collection, IEEE Transactions on Computers,
Vol c-25, No 2, pp 165-171. There are, however, many other algorithms.
