Thanks for this. For the record:
sp has a subset function for SpatialPixelsDataFrame,
but it is not exported (nor documented, I believe).
In addition, it seems not to work:
SP27GTIF_c <- sp:::subset.SpatialPixelsDataFrame(SP27GTIF_a, band1 < 100)
Error in sp:::subset.SpatialPixelsDataFrame(SP27GT

Hello list
I have been trying to figure out if it is possible to select a subset of
data in a SpatialGridDataFrame without prior conversion to a data.frame
using the method as.data.frame().
I have imported an ESRI " *. bil " file containing different spectral bands
using rgdal. The file imported
12 matches
