In maxgav13/GMisc: Miscellaneous Functions for Geology (and its areas)

Similarity Coefficient

Description

Calculates the similarity coeficient between observations based on their features (columns). Coefficient ranges between 0 and 1, with values close to 1 indicating more similarity.

Usage

similarity_coef(x, samp.names = NULL, digits = 3)

Arguments

x	A data frame of observations in rows and features (variables) in columns. Features must be non-zero and positive.
samp.names	A character vector with the names of the observations (samples)
digits	Number of digits to use

Value

A matrix of similarity coefficients
