Fortify method for classes from the sp package.

To figure out the correct variable name for region, inspect as.data.frame(model).

Usage
## S3 method for class 'SpatialPolygonsDataFrame':
fortify(model, data, region = NULL, ...)

## S3 method for class 'SpatialPolygons': fortify(model, data, ...)

## S3 method for class 'Polygons': fortify(model, data, ...)

## S3 method for class 'Polygon': fortify(model, data, ...)

## S3 method for class 'SpatialLinesDataFrame': fortify(model, data, ...)

## S3 method for class 'Lines': fortify(model, data, ...)

## S3 method for class 'Line': fortify(model, data, ...)

Arguments
model
SpatialPolygonsDataFrame to convert into a dataframe.
data
not used by this method
region
name of variable used to split up regions
...
