select_variables {DEMOVA}R Documentation

Selection of descriptors

Description

This function allow the user to select wanted descriptors between both that are intercorrelated with a correlation coefficent higher that ThresholdInterCor. The selection can also be automatic based on the correlation with the property of each variables.

Usage

select_variables(id, y, d, ThresholdInterCor, auto = FALSE)

Arguments

id

List of the names of observations

y

List of the values of the property/response

d

Dataframe containing the names of desciptors and their values (without missing or constant values)

ThresholdInterCor

Threshold value (double) of the accepted intercorrelation between descriptors (should be between 0 and 1)

auto

Two possible values: TRUE or FALSE (by default). The selection of descriptors is done automatically based on the correlation between descriptor and property (auto=TRUE) or is done manually by user (auto=FALSE)

Value

return a dataframe containing only of non intercorrelated variables

Examples

# Run after Preselection : d<-Preselection(desc)

# desc<-select_variables(id,y,d,0.95)
