plotLmPartRes: Plot partial residuals of a simple linear model fit.

In tsieger/tsiMisc: Miscelaneous utility functions, mostly related to exploratory statistical analysis

Plot partial residuals of a simple linear model fit.

Description

plotLmPartRes shows the relation between selected covariates from a lm model and the response, as well as the relation of those covariates and the response adjusted for the other covariates.

The functionality of plotLmPartRes is very limited. Only numeric vectors are supported (factors, interactions, I()'s are NOT). crPlot and ceresPlot should be preferred.

Usage

plotLmPartRes(m, covNames = names(m$model)[-1], 
    ...)

Arguments

m	an object of class 'lm'
covNames	names of covariates to plot (defaults to all of them)
...	further arguments to plot()

# fit lm
m<-lm(f~h+I(w-d),d)
