ResSel: Selection on Residuals

In coleoguy/evobir: Evolutionary Biology in R

Selection on Residuals

Description

This function takes measurements of multiple traits and performs a linear regression and identifies those records with the largest and smallest residual. Originally it was written to perform a regression of horn size on body size allowing for high and low selection lines.

Usage

ResSel(data, traits, percent = 10, identifier = 1, model = "linear")

Arguments

data	this is a dataframe with subject identifiers and phenotypic trait values
traits	a numeric vector indicating the column containing the predictor and response variables in that order
percent	the percentage of highest and lowest residuals that should be identified
identifier	the column which contains the record numbers to identify individuals
model	currently this is not used

Value

This function returns a list

high line	the ID numbers for the individuals selected for the high line
low line	the ID numbers of the individuals selected for the low line
