PhenStat (version 2.6.0)

scatterplotGenotypeWeight: Method "scatterplotGenotypeWeight"

Description

Graph function for the phenotypic dataset. Creates a scatter plot body weight versus dependent variable. Both a regression line and a loess line (locally weighted line) is fitted for each genotype.

Usage

scatterplotGenotypeWeight(phenList,depVariable=NULL,graphingName=NULL,outputMessages=TRUE)

Arguments

phenList

instance of the PhenList class; mandatory argument

depVariable

a character string defining the dependent variable of interest; mandatory argument

graphingName

a character string defining the name to be used on the graph for the dependent variable; mandatory argument

outputMessages

flag: "FALSE" value to suppress output messages; "TRUE" value to show output messages; default value TRUE
