String-type coordinates

Description

This class implements the string-type coordinates class. The coordinates are always associated with a coordinate system axis.

This class provides the specific interface for string-type coordinate values.

---

CoordinatesString$new()

Create a new coordinates instance for use with a coordinate system axis for string-type coordinate values.

Usage

CoordinatesString$new(name, direction, unit, values, attributes = list())

Arguments

name

Character string. Name of the coordinate set.

direction

Character string. Direction of the coordinates. Must be one from a set of values.

unit

Character string. Unit of measure of the coordinates.

values

A vector of values. There must be two values: the initial coordinate value and the increment.

attributes

Optional. A list of attributes of the coordinates.

Returns

An instance of this class or an error.

---

CoordinatesString$copy()

Return an exact copy of these coordinates.

Usage

CoordinatesString$copy()

Returns

A new instance of CoordinatesString.

---

CoordinatesString$subset()

Return coordinates spanning a smaller coordinate range.

Usage

CoordinatesString$subset(rng)

Arguments

rng

The range of indices to include in the returned coordinates.

Returns

A new CoordinatesString instance covering the indicated range of indices.
