# Plot the residuals of a polygenic model

## 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 confidence intervals are to be plotted.
text.size
An integer, the text size of labels.
...
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.

## Description

Plot the residuals on scatter or quantile-quantile plots.

## 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.
