Dear Murray, this seems to be a known bug in SAGA GIS, not in the RSAGA front-end:
http://www.saga-gis.uni-goettingen.de/html/index.php?module=pnForum&func=viewtopic&topic=346 Volker Wiechmann, one of the SAGA developers posted this in response to a user's note: "I am able to reproduce your error (the shapes in your zip are somewhat corrupted, but the batch file is ok). The problem arises as soon as you use a grid system or a grid as final extent/resolution destination. I had a quick look at the source but could not find something "suspicious". And I don't have the time to look in detail ... so please file a bug report on sourceforge. The module runs fine when you use a user specified extent/resolution. So maybe this is a workaround for you until the bug is fixed." The situation described above (grid used as target extent) seems to fit your problem description, so specify a fixed extent and resolution instead as a workaround. I hope this will help.

I can't, for the life of me, figure out what's going on. I need the output extents to match the extents of "filled.sgrd". RSAGA works great for everything else I have tried, but not this. Any advice?
