90th U.S. Senate Ideal Points via Optimal Classification
Description
This dataframe contains the estimated ideal points of the 90th U.S Senate
using oc
. Although it can easily be obtained from calling
the example in oc
, it is included here to facilitate illustration
of the examples for the plot and summary functions.
Usage
data(sen90oc)
Value
An object of class OCobject
, with elements as follows:
legislators |
data frame, containing all data from the old perf25.dat file about
legislators. For a typical ocObject run with an ORD file read using
readKH , it will contain the following:
state State name of legislator.
