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
