Usage

# S3 method for pffr
residuals(object, reformat = TRUE, ...)

# S3 method for pffr fitted(object, reformat = TRUE, ...)

Value

A matrix or ydata-like data.frame or a vector of residuals / fitted values (see reformat-argument)

Arguments

object

a fitted pffr-object

reformat

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()?
