EffectMethods | R Documentation |

The effects package can be used with many different classes of regression models beyond the basic models described in the `Effect`

help page. The `effSources`

function is used to tell an `Effect`

method where to find the information to compute effects. Details are given in the vignette Regression Models Supported by the effects Package. Unless you are trying to extend effects to a different class of regression model, you will have no use for this function.

## Default S3 method: effSources(mod) ## S3 method for class 'gls' effSources(mod) ## S3 method for class 'glmmPQL' effSources(mod) ## S3 method for class 'rlmerMod' effSources(mod) ## S3 method for class 'clm' effSources(mod) ## S3 method for class 'clm2' effSources(mod) ## S3 method for class 'clmm' effSources(mod) ## S3 method for class 'betareg' effSources(mod)

`mod` |
a fitted model object of the appropriate class. The default method works for many regression models for which there is no specific method. |

`Effect`

function methods by default expect regression objects to provide certain quantities, including a model formula, coefficient estimates, and the variance matrix of the estimates, in standard places. `effSources`

methods return a list of the necessary quantities if they are not in standard places.

See the vignette Regression Models Supported by the effects Package.
