distance.comb: Distance matrices combiantion

Description

This function allows combining distance matrices. The weight of each matrix must be defined by user.

Usage

distance.comb(matrices = NA, alphas = NA, method = "Corrected",
saveFile = TRUE)

Arguments

matrices

a vector of strings containing the names of the matrices to be combined

alphas

a vector of numerics containing the weight of each matrix

method

a string defining whether each distance matrix must be divided by its maximum value before the combination ("Corrected") or not ("Uncorrected"). Consequently, if the "Corrected" method is chosen, both matrices will range between 0 and 1 before to be combi

saveFile

a logical; if TRUE (default), each ouput matrix is saved in a different text file.

Value

• A matrix containing the weighted combination of the original matrices

Examples

mat1<-matrix(rep(1,16),ncol=4)
mat2<-matrix(rep(2,16),ncol=4)
mat3<-matrix(rep(3,16),ncol=4)
mat4<-matrix(rep(6,16),ncol=4)

distance.comb(matrices=c("mat1","mat2","mat3","mat4"),alphas=rep(0.25,4),
saveFile=FALSE,method="Uncorrected")
distance.comb(matrices=c("mat1","mat2","mat3","mat4"),alphas=rep(0.25,4),
saveFile=FALSE,method="Corrected")
distance.comb(matrices=c("mat1","mat2","mat3","mat4"),alphas=c(0.66,0.33,0,0),
saveFile=FALSE,method="Uncorrected")
