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 |
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.
