Plot models

Plot delay discounting models.

Usage

# S3 method for class 'td_um'
plot(
  x,
  type = c("summary", "endpoints", "link", "rt"),
  legend = TRUE,
  p_lines = NULL,
  p_tol = 0.001,
  verbose = TRUE,
  del = NULL,
  val_del = NULL,
  q_lines = c(0.025, 0.975),
  ...
)

Arguments

x

A delay discounting model. See dd_prob_model and dd_det_model.

type

Type of plot to generate.

legend

Logical: display a legend? Only relevant for type = 'summary' and type = 'rt'.

p_lines

Numerical vector. When type = 'summary' the discount curve, where the probability of selecting the immediate reward is 0.5, is plotted. p_lines allows you to specify other probabilities for which similar curves should be plotted (only applicable for probabilistic models, e.g. td_bcnm, td_bclm and td_ddm).

p_tol

If p_lines is not NULL, what is the maximum distance that estimated probabilities can be from their true values? Smaller values results in slower plot generation.

verbose

Whether to print info about, e.g., setting del = ED50 when type = 'endpoints'.

del

Plots data for a particular delay.

val_del

Plots data for a particular delayed value.

q_lines

When type = 'rt', plot dashed lines for which quantiles of the predicted RT distribution? Default is 0.025 and 0.975 (i.e., a quantile-based 95% confidence interval).

Additional arguments to plot().

Examples

if (FALSE) { # \dontrun{
data("td_bc_single_ptpt")
mod <- td_bclm(td_bc_single_ptpt, model = 'hyperbolic.1')
plot(mod, type = 'summary', p_lines = c(0.25, 0.75), log = 'x')
plot(mod, type = 'endpoints')
} # }
