plotPathProjectionCenterAndCircle {TrajectoryGeometry} | R Documentation

## Plot a path, its projection, its center and its circle

### Description

This function assumes you have a path in dimension 3 and you have found the projection for the portion under consideration, the center for its projection and the circle (i.e., radius) for the appropriate statistic. Scales the path to keep it comparable to the sphere and plots all this in your favorite color. It can be called repeatedly to add additional paths in different colors.

### Usage

    plotPathProjectionCenterAndCircle(
    path,
    from = 1,
    to = nrow(path),
    projection,
    center,
    radius,
    color,
    circleColor = "white",
    pathPointSize = 8,
    projectionPointSize = 8,
    scale = 1.5,
    newFigure = TRUE
    )

### Arguments

`path` | - A path of dimension 3 in the form of an N x 3 matrix.
`from` | - The starting place of the section under consideration. This is used for marking the relevant portion. It defaults to 1.
`to` | - Likewise. It defaults to nrow(path).
`projection` | - The projection of the relevant portion of the path.
`center` | - The center of the projection points.
`radius` | - The radius of the circle.
`color` | - The color to use for this path and its associated data.
`circleColor` | - Sets the colour of the circle. Defaults to white.
`pathPointSize` | - Sets the size of points which represent the path. Defaults to 8.
`projectionPointSize` | - Sets the size of points which represent the projected path. Defaults to 8.
`scale` | - The path will be start (its actual start) at 0 and will be scaled so that its most distant point will be at this distance from the origin. This is to keep it comparable in size to the sphere. It defaults to 1.5. Caution should be used here when plotting multiple paths.
`newFigure` | - When plotting a single figure or the first of multiple figures, this should be set to TRUE which is its default. Otherwise, set this to FALSE in order to add additional paths to the same figure.

### Value

This returns 0.

### Examples

    plotPathProjectionCenterAndCircle(path=straight_path,
                                    projection=straight_path_projection,
                                    center=straight_path_center,
                                    radius=straight_path_radius,
                                    color='red',
                                    newFigure=TRUE)
