Hi, 

	I'm currently working on ozone concentrations for my master's thesis using spatio-temporal models.  I already cleaned the data and loaded into the STFDF class of the "spacetime" package in order to visualize it.  So, I'm currently in the prediction phase.

	Since there are a lot of packages described on the CRAN's SpatioTemporal task view, and I'm only interested in fit the spatio-temporal stationary covariance functions suggested in the paper "Clases of Nonseparable, Spatio-Temporal Stationary Covariance Functions" by Noel Cressie and Hsin-Cheng Huang, I want to know if already exists a package with these classes or a package that allows me to define these models?

	My last resource is to program by myself (they used the weighted-least-squares method), but I want to avoid reinventing the wheel if something like this already exists.

Thank you in advance.

Cesar
