[R-sig-Geo] covariance matrix

[Benedikt Gräler]

Dear Erin,

you might want to take a look at the gstat function "variogramLine" and set the parameter "covariance" to TRUE. The argument "dist_vector" takes as well a distance matrix and will then return a covariance matrix. 

HTH, best wishes,

 Ben
