trimTrajectory: Trim a trajectory object to a subset of points

In BioTrajectory: Image Processing Tools for Barnes Maze Experiments

Trim a trajectory object to a subset of points

Description

This function trims the points of a 'trajectory' object by selecting a subset of the points from the specified 'from' to 'to' indices. It then creates a new trajectory using the selected points.

Usage

trimTrajectory(obj, from = 1, to = nrow(obj$points))

Arguments

obj	An object of class 'trajectory' that contains a component 'points', which is a data frame with the coordinates of the points in the trajectory.
from	A positive integer indicating the starting index of the points to include. Default is 1.
to	A positive integer indicating the ending index of the points to include. Default is the total number of rows in 'obj$points'.

Value

A new trajectory object created using the subset of points from the 'from' to 'to' indices.
