Hi ,

 

I am trying to flip a SpatialPointDataFrame vertically. The SP help on
flipVertical says that you can flip a SpatialPointDataFrame or
SpatialGridDataFrame. But when I tried using a SpatialPointDataFrame as
the argument, R comes up with an error message saying that it has to be
a SpatialGridDataFrame. I am trying to overlay a SpatialPolygonDataFrame
on SpatialPointDataFrame and counts the number of points falling into
each polygon. Before I do that I need to flip the points data frame
vertically. I would appreciate very much if you could help me out by
telling me what I am doing wrong or is there a better a way of getting
the overlay job done, given that I need to flip the points data frame.

 

Thanks
