predict_traj_input_validation: Internal function to validate inputs to trajectory prediction...

In transittraj: Reconstruct and Visualize Transit Vehicle Trajectories

Internal function to validate inputs to trajectory prediction methods.

Description

Checks that the proper combination of inputs is provided. Should be one of: new_times; new_distances; distance_lims AND timestep. If latter or new_distances, trajectory must also have inverse function. Derivative is also checked against maximum allowed.

Usage

predict_traj_input_validation(
  new_times,
  new_distances,
  distance_lims,
  timestep,
  has_inv,
  deriv,
  max_deriv
)

Arguments

new_times	A DF or vector of new time values, or NULL
new_distances	A DF or vector of new distance values, or NULL
distance_lims	A vector of min, max distance, or NULL
timestep	An integer for interpolation timestep, or NULL
has_inv	Boolean, does traj have inv fun?
deriv	vector of numeric derivs to interpolate at
max_deriv	Maximum derivative supported by traj fun

Value

Throws error only if not all OK
