getData.lme {nlme} | R Documentation |
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.
