Parameter estimates are plotted along with error bars indicating 95 pct confidence intervals.

1 |

`...` |
One or more models. Currently, |

`intercept` |
Logical indicating whether the intercept should be plotted (defaults
to |

`par` |
Which model parameters to plot estimates for, given as character strings.
Default is |

`colors` |
Color scale to use if several models are plotted. Defaults to a color blind friendly scale. If there are more models than there are colors, the color values are repeated. |

One or more models can be supplied, and if the parameters have the same names across models, they will be grouped together allowing for easy comparison.

Note that models can be given with or without names. If names are supplied (see example below), these are printed in the plot legend. Otherwise, the name of the model object is printed there instead.

Implementation details: As a default, the estimates are extracted
from the `$coefficients`

slot from the model object and
confidence intervals are computed by calling `confint()`

. This
means that `plotEst`

supports all models that have a
`coefficents`

slot and a `confint`

method.

No return values; called for side effects.
