| extractRollCallObject {pscl} | R Documentation |
Given a fitted model of class ideal, return the
rollcall object that was used in the model fitting
(i.e., apply all subseting and recoding implied by the dropList
passed to ideal).
extractRollCallObject(object)

an object of class ideal |
This function is used by many post-estimation commands that operate on
objects of class ideal. The function inspects the
call attribute of the
ideal object, extracting the name of the
rollcall object and the dropList, then hands them
over to dropRollCall.
