Initiation Time — time_circle_left • mousetRajectory

Checks when the specified circle was first left by a trajectory.

Usage

time_circle_left(
  x_vector,
  y_vector,
  t_vector,
  x_mid = 0,
  y_mid = 0,
  radius = 1,
  include_radius = TRUE,
  warn = TRUE
)

Arguments

x_vector: x-coordinates of the executed path.
y_vector: y-coordinates of the executed path.
t_vector: Timestamps of the executed trajectory.
x_mid: x-coordinate of the center of the circle.
y_mid: y-coordinate of the center of the circle.
radius: radius of the center of the circle.
include_radius: Whether points lying exactly on the radius should be included in the circle. Defaults to TRUE.
warn: whether a warning should be thrown if the first entry of t_vector is returned. Defaults to TRUE.

Value

Value of t_vector at the first time at which the trajectory is out of the circle.
