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

[Rawlins, Barry G.]

Hi Edzer

I can see a series of folders+files on the svn area - can you just give me some direction on how I get the source code? Were you suggesting I just take the code under R/stplot.R? And build a function from this?

Best wishes, Barry

svn co https://svn.52north.org/svn/geostatistics/main/spacetime/

will give you the updated source. Let me know if it works, otherwise
we'll try the CRAN route (CRAN seems a bit over-worked, lately, for
clear reasons, throwing NOTEs if you're uploading too frequent).

I just noticed that the package DESCRIPTION file does not contain this
URL -- will modify.
