[R] X-fold cross validation function for discriminant analysis

[Christos Hatzis]

Apologies for the typos there.
I meant to say see the Bioconductor web site for details.

One option is the Bioconductor package MLInterfaces that provides a unified
interface for several machine learning alrogirithms and methods for
cross-validation etc.  See the algorithms web site for details.
