findMax {DisimForMixed} R Documentation

## Calculate Distance Between given Attribute Values by considering only a pair of attributes.

### Description

Takes in two lists Ai and Aj, representing values of two attributes, two values x and y from Ai. Quantitative attributes are accepted only after descretization. Calculates distance between x and y for Aj with respect to Ai.

### Usage

findMax(Ai, Aj, x, y)


### Arguments

 Ai A list consisting values of a selected attribute Aj A list consisting values of another selected attribute x Value from Ai y Another value from Ai

### Details

### Examples

Attrib_i <- c("A","B","A","C")
Attrib_j <- c("Q","Q","R","Q")
xVal <- "A"
yVal <- "B"
QualiVars <- data.frame(Qlvar1 = c("A","B","A","C"), Qlvar2 = c("Q","Q","R","Q"))
library(dplyr)
distBetXY <- findMax(Attrib_i,Attrib_j,xVal,yVal)
