Plot Dynamic Person Ideal Points (Deprecated)

  low_limit = 0.05,
  line_size = 1,
  highlight = NULL,
  plot_text = TRUE,
  use_ci = TRUE,
  plot_lines = 0,
  draw_line_alpha = 0.5,
  person_line_alpha = 0.3,
  person_ci_alpha = 0.8,
  item_plot_type = "non-inflated",
  show_true = FALSE,
  group_color = TRUE,
  hpd_limit = 10,
  sample_persons = NULL,
  use_chain = NULL,
  add_cov = TRUE,
  ...
)

Arguments

object	A fitted idealstan object or a named list of idealstan objects if the plot is supposed to show a comparison of different fitted idealstan models (see Time Series vignette)
return_data	If true, the calculated legislator/bill data is returned along with the plot in a list
include	Specify a list of person/legislator IDs to include in the plot (all others excluded)
item_plot	The value of the item/bill for which to plot its midpoint (character value)
text_size_label	ggplot2 text size for legislator labels
text_size_group	ggplot2 text size for group text used for points
high_limit	A number between 0 and 1 showing the upper limit to compute the posterior uncertainty interval (defaults to 0.95).
low_limit	A number between 0 and 1 showing the lower limit to compute the posterior uncertainty interval (defaults to 0.05).
line_size	Sets the size of the line of the time-varying ideal points.
highlight	A character referring to one of the persons in person_labels that the plot can highlight relative to other persons
plot_text	If TRUE, will plot person_labels over the lines.
use_ci	Whether or not high-posterior density intervals (credible intervals) should be plotted over the estimates (turn off if the plot is too busy)
plot_lines	The number of lines of actual draws of time-varying ideal points to draw on the plot. Note that these are grouped by persons. Specific draws selected at random from total number of draws of the estimation. Default is 0.
draw_line_alpha	The opacity of lines plotted over the distribution (should be between 0 and 1, default is 0.5).
person_line_alpha	The transparency level of the time-varying ideal point line
person_ci_alpha	The transparency level of ribbon confidence interval around the time-varying ideal points
item_plot_type	Whether to show the 'non-inflated' item/bill midpoints, the 'inflated' item/bill midpoints, or produce plots for 'both' kinds of models. Defaults to 'non-inflated' and will only display an item/bill midpoint if one has been specified in item_plot.
show_true	Whether to show the true values of the legislators (if model has been simulated)
group_color	If TRUE, use the groups instead of individuals to plot colours
hpd_limit	The greatest absolute difference in high-posterior density interval shown for any point. Useful for excluding imprecisely estimated persons/legislators from the plot. Leave NULL if you don't want to exclude any.
sample_persons	If you don't want to use the full number of persons/legislators from the model, enter a proportion (between 0 and 1) to select only a fraction of the persons/legislators. (see id_sim_gen())
use_chain	ID of MCMC chain to use rather than combining all chains. Default is NULL which will use all chains and is recommended.
add_cov	Whether to add values of hierarchical person-level covariates to the time trends (defaults to TRUE).
...	Other options passed on to plotting function, currently ignored

Value

A ggplot2 object showing dynamic legislator/person ideal points over time. Deprecated; use id_plot_persons_dyn instead.
