update.clm2

Update method for cumulative link models

Update method for cumulative link models fitted with clm2. This makes it possible to use e.g. update(obj, location = ~ . - var1, scale = ~ . + var2)

Usage
# S3 method for clm2
update(object, formula., location, scale, nominal,...,
        evaluate = TRUE)
# S3 method for clmm2
update(object, formula., location, scale, nominal,...,
        evaluate = TRUE)
Arguments
object

a clm2 object.

formula.

not used---unfortunately this argument is part of the default method.

location

an optional new formula for the location; see update.formula for details.

scale

an optional new formula for the scale; see update.formula for details.

nominal

an optional new formula for nominal effects; see update.formula for details.

additional arguments to the call, or arguments with changed values.

evaluate

if true evaluate the new call else return the call.

Value

If evaluate = TRUE the fitted object is returned, otherwise the updated call.
