SilhouetR: SilhouetR

In speaq2: Wavelet Based Tools for Feature-Wise Analysis and Quantification of Nuclear Magnetic Resonance (NMR) Spectra

Description

Calculate the Silhouette value for

Usage

SilhouetR(DataMatrix, GroupIndices, distance = "euclid", stand = TRUE)

Arguments

DataMatrix	a matrix with the raw data, 1 variable per column.
GroupIndices	The vector with the roup indices (length must be equal to the amount of rwos in DataMatrix).
distance	The distance metric to be used, see daisy.
stand	whether to standardize the data before calculating the dissimilarities. See daisy.

Value

Returns the silhouette values.
