Subject: shp file with 2 types of bodies (water and forest)
I would like to map the forests in green and the water bodies in blue :
summary(nature)
Object of class SpatialPolygonsDataFrame
Coordinates:
min max
r1 2.560776 6.403847
r2 49.493613 51.505419
Is projected: FALSE
proj4string : [+proj=longlat]
Data attributes:
NAME TYPE
Dijle : 43 forest:6830
Schelde : 30 water :6564
Ringselven : 17
Albertkanaal : 15
Westelijke Rijkswaterleiding: 14
(Other) : 990
NA's :12285
How do I ask R to map, for example, only the forests ?
