tr.asreml {asreml} | R Documentation

## Convergence trace for asreml objects.

### Description

Scatter plots of component value against iteration for each random component.

### Usage

    ## S3 method for class 'asreml'
    tr(
      object,
      components = seq(5, 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, 3 and 4.
`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) four rows of this matrix corresponding to `LogLik`, `Sigma2`, `DF` and `stepsz`, respectively, are not plotted by default.

### Value

An invisible list of `ggplot2` objects.
