corRSpher
(Package: ramps) :
Spherical Spatial Correlation Structure
This function is a constructor for the 'corRSpher' class, representing a spherical spatial correlation structure. Letting r denote the range, the correlation between two observations a distance d < r apart is 1-1.5(d/r)+0.5(d/r)^3. If d >= r the correlation is zero.

corRExpwr2
(Package: ramps) :
Non-Separable Powered Exponential Spatio-Temporal Correlation Structure
This function is a constructor for the 'corRExpwr2' class, representing a non-separable spatial correlation structure. Letting rs denote the spatial range, ps the spatial shape, rt the temporal range, pt the temporal shape, and lambda the space-time interaction, the correlation between two observations a distance d apart in space and t in time is exp(-(d/rs)^ps - (t/rt)^pt - lambda * (d/rs)^ps * (t/rt)^pt).
