[R-sig-Geo] How to use covariate files for regression kriging

[Shabir A.Bangroo]

Hi all,

I am new to R and geostatistics.
I have raster files (NDVI and DEM) and I want to use them as covariates for
regression kriging.
Do I need to project them first to same projected coordinate system
and resample
to same cell size before converting them to txt file for use in r.

Thanks
