Vivien, the following might give you some pointers:
library(spacetime)
vignette(stpg)
edit(vignette(stpg))
to run the postGIS thing, you have to uncomment all the eval=FALSE sections.
Not sure if Edzer's
Hi,
I'm trying to use gmap function from dismo.
I apply the example but it gives me an error message 'Cannot create a

Hi,
I'm putting together a package to do some analysis that uses the great
features provided by raster package. I'm anticipating reading a large
number of rasters (tens of thousands in my test case), lined up into a
single rasterStack. At any given time, I only need to operate on a

Dear Users,
I'm new learning R and I have several Era_Interim datasets (from ECMWF Global
re-analysis data) to analyze. Any help with a guide script will be appreciated.

Ah, thanks for pointing out the definition of cell order. The
documentation for raster::values doesn't specify that
values(rasterLayer, format = ) always returns values in cell order,
nor does it state that values(rasterStack) or values (rasterBrick)
returns rows in cell order, so I wanted to
