Plot DDM Data

Plot data.

Usage

ddm_plot(data, ...)

ddm_plot_upper(
  data,
  density = NULL,
  xlim = c(0, 2),
  hist_alpha = 1/3,
  density_linewidth = 1,
  theme = "default",
  ...
)

ddm_plot_lower(
  data,
  density = NULL,
  xlim = c(0, 2),
  hist_alpha = 1/3,
  density_linewidth = 1,
  theme = "default",
  ...
)

ddm_plot_traces(
  traces,
  trace_alpha = 0.8,
  trace_linewidth = 0.5,
  xlim = c(0, 2),
  theme = "default",
  ...
)

Arguments

data

Either object from ddm_data()) or dataframe containing columns "rt", "response" (lower or upper) and "condition".

...

Other arguments to pass to other functions, such as additional controls to hist().

density

Data for density lines (typically obtained from ddm_data()).

xlim

X-axis limits.

theme

Can be NULL (useful for customizing) or "default".

traces

Data for trace lines (typically obtained from ddm_data()).

trace_alpha, hist_alpha

Alpha of trace lines or histograms.

trace_linewidth, density_linewidth

Alpha of trace lines or histograms.

Examples

library(ggplot2)
#> Warning: package 'ggplot2' was built under R version 4.2.2
library(patchwork)

# Simulate data
sim <- ddm_data(n=1000, drift = c(1, 0), n_traces = 20)

ddm_plot(sim, xlim = c(0, 1))


# Customize
data <- sim$data
density <- sim$density
traces <- sim$traces

ddm_plot_upper(data, density = density, theme = NULL) /
  ddm_plot_traces(traces, theme = NULL) /
  ddm_plot_lower(data, density = density, theme = NULL)
