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.
