Description
Fit a principal curve in K dimensions.Usage
## S3 method for class 'matrix':
normalizePrincipalCurve(x, ..., center=TRUE, returnFit=FALSE)
Arguments
x
An NxK matrix (K>=2) where the columns represent the dimension. center
If TRUE, normalized data is centered such that the median
signal in each dimension is at zero. returnFit
If TRUE, the fitted principal curve parameters are
