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

[Benedikt Gräler]

Dear list members,

motivated by a post from Erin Hodgess earlier this week, I put together
an "interactive spatio-temporal variogram exploration tool". It is a
shiny app based on gstat and is available at:

http://giv-graeler.uni-muenster.de:3838/spacetime/

The code of this shiny app can be obtained from github:

https://github.com/BenGraeler/copulatheque/tree/master/spacetime

After downloading the files, the shiny app should as well run locally
(using the shiny package from CRAN).

For numerical optimisation of the (pre-selected) parameters, the gstat
function "fit.StVariogram" (based on "optim") might be a helpful tool.

I hope this will be helpful to some of you,

 Ben
