normalizePrincipalCurve.matrix

Normalizes data in K dimensions using principal curves such that afterward the data cluster (approximately
 linearly) along the diagonal (in K dimensions).

Methods for analyzing DNA copy-number data.  Specifically,
this package implements the multi-source copy-number normalization (MSCN)
method for normalizing copy-number data obtained on various platforms and
technologies.  It also implements the TumorBoost method for normalizing
paired tumor-normal SNP data.
