Description
plot.asreml: Four plots are generated: a histogram of the residuals, a Normal Q-Q plot, a plot of residuals against fitted values and a plot of residuals against unit number.
Usage
## S3 method for class 'asreml' plot(x, res = "default", spatial = "trend", facet = FALSE, ...)
Arguments
x |
An asreml object. |
res |
The type of residuals; see residuals.asreml. |
spatial |
If “plot” and an independent error has been fitted with units in the random formula, these are added to the residuals, otherwise if “trend” (the default) then units are not added even if present in the model. |
facet |
If TRUE, multi-panel conditioning plots are produced for models with multi-section residual structures. |
... |
Additional arguments. |
Details
If the residual structure of the model contains multiple sections, the default plots are conditioned on the factor whose levels define the sections. For multivariate analyses, the plots are conditioned on trait.
Value
An invisible list of ggplot2 objects.
