See predict.pffr for alternative options to extract estimated
values from a pffr object.
"Fitted values" here refers to the estimated additive predictor values,
these will not be on the scale of the response for models with link functions.
# S3 method for pffr
residuals(object, reformat = TRUE, ...)# S3 method for pffr
fitted(object, reformat = TRUE, ...)
A matrix or ydata-like data.frame or a vector of
residuals / fitted values (see reformat-argument)
a fitted pffr-object
logical, defaults to TRUE. Should residuals be returned in
n x yindex matrix form (regular grid data) or, respectively, in the
shape of the originally supplied ydata argument (sparse/irregular
data), or, if FALSE, simply as a long vector as returned by
resid.gam()?
other arguments, passed to residuals.gam.
