showTrajectory: Displays a trajectory plot from a set of coordinates.

In BioTrajectory: Image Processing Tools for Barnes Maze Experiments

Displays a trajectory plot from a set of coordinates.

Description

Visualizes the trajectory represented by a series of points. The function can display the full trajectory or a subset based on a specified step size. It supports customizable color palettes for enhanced visualization.

Usage

showTrajectory(data, stepSize = 0, pal)

Arguments

data	A data frame containing the trajectory coordinates with columns 'x' and 'y'.
stepSize	An integer specifying the interval for plotting segments of the trajectory. If set to 0, the entire trajectory is plotted. Default is 0.
pal	A color palette to be used for plotting the trajectory segments.

Value

A plot displaying the trajectory based on the provided coordinates and settings.

Examples

# Generate example trajectory data
path <- system.file('extdata/track.txt', package='BioTrajectory')
data <- BioTrajectory::readtrackData(path)
data <- na.omit(data)
palette <- grDevices::colorRampPalette(c("purple","blue","cyan","yellow","orange","red"))
# Show the full trajectory
showTrajectory(data, stepSize = 0, pal = palette)
# Show the trajectory with a step size of 36
showTrajectory(data, stepSize = 36, pal = palette)
