[R-sig-Geo] interactive spatio-temporal variogram exploration

[Hodgess, Erin]

For what it's worth, I'm working on an RcmdrPlugin package to do kriging and maps and maybe spatio-temporal stuff, if anyone might be interested

Dear Benedikt,

Many thanks for your nice example!! I am wondering whether it could be
possible to modify your code to allow the user to upload a file with the
data to be used. For example, a 3-column CSV file with x, y and variable
value. I am not a shiny user so I am not sure whether this is possible
at all. I'd like to try a similar approach for disease mapping where the
user can upload disease data plus boundaries and then try some spatial
smoothing models.

Best wishes,

Virgilio
