The presence of an intercept is checked using the formula which is either provided as the argument of the function or extracted from a fitted model
has.intercept(object, ...)# S3 method for default
has.intercept(object, ...)
# S3 method for formula
has.intercept(object, ...)
# S3 method for Formula
has.intercept(object, rhs = NULL, ...)
# S3 method for panelmodel
has.intercept(object, ...)
# S3 method for plm
has.intercept(object, part = "first", ...)
a formula
, a Formula
or a fitted model (of class
plm
or panelmodel
),
further arguments.
the index of the right hand sides part of the
formula for which one wants to check the presence of an
intercept (relevant for the Formula
and the plm
methods),
a boolean
