Summary function for AVL trajectories.

This function prints a summary for grouped or single trajectory object If the input is a single trajectory, the trip's ID and distance & time range will be printed. If the input is a grouped trajectory, the number of trips and the distance & time range across all trips will be printed. For both, the interpolating curve methods will be printed.

Usage

# S3 method for class 'avltrajectory_group'
summary(object, ...)

# S3 method for class 'avltrajectory_single'
summary(object, ...)

Arguments

object

A single or grouped trajectory object.

...

Other parameters (not used).

Value

A summary character string.

Examples

# Get input data
c53_traj_grouped <- new_transittraj_data("get_trajectory_fun")
c53_traj_singles <- new_transittraj_data("get_trajectory_fun_single")
