idealstan (version 0.7.1)

id_plot_compare: Function to compare two fitted idealstan models by plotting ideal points. Assumes that underlying data is the same for both models.

Description

Function to compare two fitted idealstan models by plotting ideal points. Assumes that underlying data is the same for both models.

Usage

id_plot_compare(model1 = NULL, model2 = NULL, scale_flip = FALSE,
  return_data = FALSE, labels = NULL, hjust = -0.1,
  palette = "Set1", color_direction = 1, text_size_label = 2,
  rescale = FALSE)

Arguments

model1

The first model to compare

model2

The second model to compare

scale_flip

This parameter is set to true if you have two models that are reflected around the ideal point axis. This can happen as a result of identification and is harmless.

return_data

Whether to return the underlying data

labels

TRUE or FALSE, whether to use labels for points

hjust

The horizontal adjustment of point labels

palette

colorbrewer palette name

color_direction

Whether to reverse the color scale

text_size_label

Size of point labels

rescale

Whether to rescale the estimates from two models so they will match regardless of arbitrary scale shifts in the ideal points
