[R-sig-Geo] stConstruct with multiple SpatialPolygonsDataFrame objects

Hi, Can anyone provide an example of using stConstruct() with multiple SpatialPolygonsDataFrame objects? I have created the latter by reading in multiple shapefiles, one shapefile per year. Each shapefile contains polygons at several levels of an attribute. I want to plot these polygons for l

[R-sig-Geo] spatio temporal anisotropy: help with stAni argument

Hi, I have some problems in understanding the usage of argument 'stAni' of vgmST and krigeST functions, for.the setting of spatio temporal anisotropy. How have I to interpret this argument, that is the integer value that I saw I have to assign to it, what does it means? How can this argument influe
