plot.aldmck_negative: Aldrich-McKelvey Negative Coordinate Distribution Plot

Description

plot.aldmck_negative reads an aldmck object and plots the probability distribution of the respondents and stimuli with negative weights.

Usage

## S3 method for class 'aldmck_negative':
plot(x, xlim=c(-2,2), ...)

Arguments

x

an aldmck output object.

xlim

vector of length 2, fed to the plot function as the xlim argument, which sets the minimum and maximum range of the x-axis.

...

other arguments to plot.

Value

• A plot of the probability distribution of the respondent ideal points, along with the locations of the stimuli. If no negative weights exist, either because respondent self-placements are not specified, or because all weights are positive, a plot indicating this in text is given.
