as.MAPraster: Convert Raster objects into MAPraster objects

Description

as.MAPraster converts a RasterLayer or RasterStack object into a 'MAPraster' object (data.frame) for easy plotting with ggplot.

Usage

as.MAPraster(raster_object)

Value

as.MAPraster returns a MAPraster object (data.frame) containing the below columns.

1. x - x coordinates of raster pixels

2. y - y coordinates of raster pixels

3. z - value of raster pixels

4. raster_name - name of raster for which values are stored in z

Arguments

raster_object

RasterLayer or Rasterstack object to convert into a MAPraster.
