R: REML convergence trace for 'asreml' objects.

tr.asreml {asreml}

R Documentation

REML convergence trace for `asreml` objects.

Description

Scatter plots of model component values against iteration for each random component for a fitted model.

Usage

## S3 method for class 'asreml'
tr(
  object,
  components = seq(4, nrow(object$trace)),
  iter = seq(1, ncol(object$trace)),
  ...
)

Arguments

object

An asreml object.

components

A numeric vector of row numbers of the trace matrix to include; default is all rows excluding rows 1, 2 and 3.

iter

A numeric vector of iteration numbers to include; default is all columns of trace.

...

Additional arguments.

Details

Values are extracted from the trace matrix of an asreml fitted object. The (first) three rows of this matrix corresponding to LogLik, Sigma2 and DF, respectively, are not plotted by default.

Value

An invisible list of ggplot2 objects.
