congruencePlot: Congruence Plot

In polrep: Calculate Political Representation Scores

Congruence Plot

Description

Plots congruence.

Usage

congruencePlot(Z, R, from=NA, to=NA, steps=10000, Zcol=1, Rcol=1,
Zlty=1, Rlty=2, Pcol=220, Pdensity=NULL, Pangle=45, ...)

Arguments

Z	Population vector
R	Vector for the representatives
from	Beginning of conceptual space
to	End of conceptual space
steps	Number of steps at which to evaluate the CDF
Zcol	Line colour for the population vector
Rcol	Line colour for the vector of the representatives
Zlty	Line type for the population vector
Rlty	Line type for the vector of the representatives
Pcol	Colour of the polygon
Pdensity	Density of the polygon's pattern
Pangle	Angle of the polygon's pattern
...	Additional arguments for the plot

Details

This function plots the cumulative distributions of the population vector an the vector for the representatives. A polygon highlights the area between the two curves. The basic arguments are the same as for the congruence function which calculates the area between the two curves; the additional arguments are used to control the lines (colour, type) and polygon (colour, pattern). Use Pcol=NULL to hide the polygon entirely. The beginning and end of the conceptual (policy) space can be specified if the vectors do not include the entire range of possible values. The number of steps at which the CDF are evaluated can be specified (default = 10000). Additional arguments can be passed to control the plot, like main title or axes.
