[R-sig-Geo] Plotting with stplot, mode="xy"

[Rawlins, Barry G.]

Daniel and Edzer

I managed to build the stplot.R function and get that working - so thanks for that. The "cut" argument works fine and the scale does not change now as the animation runs. For some reason I needed to make the bin range (min and max) wider than the range of the data to make sure all the xy locations plotted in every amimation (some were dropped otherwise)  - I am not sure why that would be the case.

I will look for some instructions (presumably on other help lists) on how to build a package from the source as that is not something I have done before, but will be pleased to learn.

Best wishes, Barry

The svn also has http access, so

source("https://svn.52north.org/svn/geostatistics/main/spacetime/R/stplot.R")

should do just that.
