## 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.
- ...
- 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.

## 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.

## Not run:
# ### basic (univariate) polygenic model
# mod <- solarPolygenic(trait1 ~ age + sex, dat30)
#
# plotRes(mod)
