Description

Plots individual representation scores based on frequency vectors.

Usage

1
irs.plot(G, H, perspective = "individual", groups=c("Voters","MP"), concept="Ideology")

Arguments

G

frequency vector for the population

H

frequency vector for the representatives

perspective

individual perspective (default) or population perspective

groups

label for the frequency vectors

concept

label for the concept measures

Details

This function plots individual representation scores for categorical data. As with the underlying irs.cat, you will need two frequency vectors, one for the population, and one for the representatives. The two frequency vectors need to be of the same length. Use the argument groups to specify what these frequency capture. The default labels are ‘Voters’ and ‘MP’. You can also specify the concept measured, such as left-right or social policies (default label: ‘ideology’. It is further possible to choose the perspective of the population, which leads to slightly different individual representation scores for small N.

The plots show the frequency distributions of the two vectors supplied at the top, and the resulting individual representation scores for each category.

# Sample data
G <- c(1,5,10,15,3)
H <- c(0,3,0,5,1)
# Calculate individual representation scores
irs.cat(G,H)
# Plot this:
irs.plot(G,H)
