calculate_MSSI: Function to calculate the Multiscale Straightness Index

In pennekampster/MSSI: The multiscale straightness index for the analysis of animal trajectories

Description

Takes a dataframe with the X and Y coordinates of a trajectory and calculates the MSSI for different window sizes and granulosities.

Usage

calculate_MSSI(data, uniqueID = "traj", time = "frame", window_size,
  granulosity)

Arguments

data	A dataframe containing the X and Y coordinates
uniqueID	The unique identifier for each trajectory in the dataframe
time	The column containing the information on the time for each fix
window_size	A numeric value or vector specifying the window sizes over which the MSSI should be calculated
granulosity	A numeric value or vector specifying the temporal resolution of the data before the MSSI is calculated

Value

A dataframe containing the MSSI for each fix in addition to the input data
