Generate a Simulated Eye-Movement Data Frame

The `simulate_eye_table` function generates a simulated `eye_table` object containing eye-movement data with columns for x and y coordinates, fixation duration, onset time, and an optional grouping variable.

Usage

simulate_eye_table(
  n_fixations,
  n_groups,
  clip_bounds = c(0, 1280, 0, 1280),
  relative_coords = TRUE
)

Arguments

n_fixations

The number of fixations to simulate.

n_groups

The number of groups to simulate.

clip_bounds

A numeric vector of length 4 representing the clip bounds for the field of view in the form c(xmin, xmax, ymin, ymax). Default is c(0, 1280, 0, 1280).

relative_coords

A logical value indicating whether to compute relative coordinates (TRUE by default). If TRUE, x and y coordinates will be transformed based on the clip_bounds.

Value

A `data.frame` of class "eye_table" with simulated data.

Examples

sim_eye_table <- simulate_eye_table(n_fixations = 100, n_groups = 10)
#> Error in select_at(., c("x", "y", "duration", "onset", groupvar)): could not find function "select_at"
