R: Importing JavaScript coordinate information.

Import Coordinate JS {gridSVG} | R Documentation

## Importing JavaScript coordinate information.

### Description

This function reads in a JavaScript file and transforms it into JSON text. This text is then transformed into a list that can be used in conjunction with `gridSVGCoords`.

### Usage

    readCoordsJS(filename)

### Arguments

`filename` | A character vector that represents a file name. This file should be a JavaScript file containing coordinate information produced by `grid.export`.

### Details

In order to use the `fromJSON` function to parse JSON text, the JavaScript file produced by `grid.export` needs to be transformed. It needs to transform from being an assignment of an object literal to simply the object literal itself.

This function performs that task by producing a valid JSON string ready for parsing by `fromJSON`. It then returns the parsed list.

### Value

A list of coordinate information.
