Dear All,
I'm trying to understand how spplot work with colour managing with gridded
data.
I have na Object of class SpatialGridDataFrame
Coordinates:
min max
x 2267600 2325600
y 4693800 4826200
Is projected: TRUE
proj4string :
with 12 data for column attribute
I'm able to plot the SpatialGridDataFrame with:
spplot(fogli_Sup_Pioggia,as.table=TRUE, col.regions = cm.colors(100) ,
key.space = "right")
but I want to select where change in colour appears and not leave spplot to
do it by it self.
I tried passing cuts option in this way:
spplot(fogli_Sup_Pioggia,as.table=TRUE, col.regions = cm.colors(100) ,
cuts=c(1,2.5,3),key.space = "right")
It seems working but now the colour is not graduated any more but.
How can I have a graduated palette again?
Thanks
