getData.lme

Extract lme Object Data


Description

If present in the calling sequence used to produce object, the data frame used to fit the model is obtained.

Usage

## S3 method for class 'lme'
getData(object)

Arguments

object

an object inheriting from class lme, representing a linear mixed-effects fitted model.

Value

if a data argument is present in the calling sequence that produced object, the corresponding data frame (with na.action and subset applied to it, if also present in the call that produced object) is returned; else, NULL is returned.

Note that as from version 3.1-102, this only omits rows omitted in the fit if na.action = na.omit, and does not omit at all if na.action = na.exclude. That is generally what is wanted for plotting, the main use of this function.
