## 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`
