plotRes: Plot the residuals of a polygenic model

Description

Plot the residuals on scatter or quantile-quantile plots.

Usage

plotRes(x, labels = FALSE, text.size = 4, ...)
plotResQQ(x, distribution = "norm", ..., line.estimate = NULL, conf = 0.9,
  labels = FALSE, text.size = 4)

Arguments

x

An object of class solarPolygenic.

labels

A logical value for plotRes function, indicating if the labels of IDs (which residuals are outside the 3 * sd interval) are to be plotted. A logical value for plotResQQ function, indicating if the samples (their IDs) outside the

text.size

An integer, the text size of labels.

...

additional arguments.

distribution

A character, name of distribution of the residuals. The default value is "norm".

line.estimate

Function for estimation of QQ-line.

conf

A numeric value between 0 and 1, that represents the confidence boundary.

Details

plotRes function makes a scatter plot of fitted values vs. residuals. Note that the residuals returned by SOLAR include both random effects, i.e. house-hold, genetic and residuals itself.

plotResQQ function plots quantile-quantile (QQ) plot of the residuals.
