Source: R/plot_respondents.R
plot_respondents.Rd

Plot the distribution of estimated respondent positions from an HBAM model.

Usage

plot_respondents(
  object,
  inc_stimuli = TRUE,
  n_draws = 15,
  color = "#053061",
  fill = "#2166AC",
  alpha_color = 0.6,
  alpha_fill = 0.7/n_draws,
  seed = 1
)

Arguments

object

An instance of class stanfit produced by hbam().

inc_stimuli

Logical: Should estimated stimulus positions also be shown?

n_draws

Integer specifying the number of posterior draws to use when illustrating the uncertainty of the population distribution. Defaults to 15.

color

Color of lines illustrating uncertainty.

fill

Fill color for density plots.

alpha_color

Number in [0,1]: Inverse level of transparency for line color.

alpha_fill

Number in [0,1]: Inverse level of transparency for fill color.

seed

A positive integer specifying an optional seed for reproducibility. The seed is used to select respondent position draws for illustrating uncertainty.

Value

A ggplot object.
