pathProgression {TrajectoryGeometry} | R Documentation

## Measure a path's progression

### Description

This function measures the progress of a path in a specified direction. This direction will typically be the center of its projection onto the sphere as revealed using your favorite statistic.

### Usage

    pathProgression(path, from = 1, to = nrow(path), d = ncol(path), direction)

### Arguments

`path` | - An n x d matrix
`from` | - The point along the path to be taken as the starting point. This defaults to 1.
`to` | - The point along the path to be used as the end point. This defaults to nrow(path).
`d` | - The dimension to be used. This defaults to ncol(path).
`direction` | - A non-zero numeric whose length is the the dimension.

### Value

This returns a numeric given the signed distance projection of the path along the line through its starting point in the given direction.

### Examples

    progress =
        pathProgression(straight_path,direction=straight_path_center)
    progress =
        pathProgression(crooked_path,from=6,direction=crooked_path_center)
