Hi,
Kriging is never done on a txt file or a csv file, but on an R object.
For gstat this is a SpatialPointsDataFrame and for geoR this is another
type of object. CVS files, txt files (what is the difference?) and
shapefiles can all be read into SpatialPointsDataFrame's. For reading
shapefiles, see the rgdal package.
