You are still using the deprecated interface that accepts data.frame
objects as input.
Please see demo(cokriging) to find out how the interface with Spatial*
objects works, and read ?proj4string to find out how to specify
projection systems for such objects.

Hi all,
I am new to geostatistics and need some help on projection. I am working on a
bivariate model of a sphere and want to do cokriging with gstat package in R.
My data look like
> head(mydata)
lon lat v1 v2
1 2.1238698 0.87854240 1.8051750 1.044
2 -2
