findSphericalDistance {TrajectoryGeometry} | R Documentation

## Find the spherical distance from a given point to a set of points.

### Description

This function takes a point (typically a center) and a set of points and finds the spherical distance between the given point and each of the others. If requested, it will first normalize all of them.

### Usage

    findSphericalDistance(center, points, normalize = FALSE)

### Arguments

`center` | - The proposed point from which distance to the others should be measured. This is a numerical vector of length d.
`points` | - The set of target points for which spherical distance to the center should be calculated. This is in the form of a n x d matrix.
`normalize` | - If this is set to TRUE, the function will start by normalizing the input points.

### Value

This returns a vector of n spherical distances in radians.

### Examples

    distances = findSphericalDistance(straight_path_center,
        straight_path_projection)
