[R-sig-Geo] Spatio-Temporal objects and kriging

[Bruno Sesti]

Hi, I have some questions about spatio temporal objects and kriging, I have
done some research to try to solve this problems but I did not find any
answer.
I would Like to know if and, if yes, how could be possible to convert a
STIDF object to a SpatialPointsDataFrame object.
The second issue is if and how it could be possible to plot the map(s)
obtained through the function krigeST over an open street map or a Google
map layer in R environment and/or in other gis environments.

Kind regards.
