[R-sig-Geo] Problems generating RasterStack object

[Francisco Rodriguez Sanchez]

Hi Gerardo,

It would help if you could provide a reproducible example to spot the 
problem... Anyway, try the spatial_sync_raster function in the 
spatial.tools package 
(http://cran.at.r-project.org/web/packages/spatial.tools/index.html). It 
will easily match the projection, resolution and extent of your rasters 
to a reference raster

Hope it helps

Paco
