Hi all...
Does anybody have a digcap entry (i.e. grass 4.1 v.digit configuration) for a Summasketch digitiser? We have 3 flavours, from a 'plus' to a 'III professional', so a lowest-common-denominator configuration is what I'm after.
We are in the market for some new digitisers. Any good or bad experiences with particular brands/models that you would care to share? (e.g. value for money, dog to set up under grass, etc)
..........
Thoughts for the day on grass-Splus communication:
Why not create a named pipe (with mknod p), then start up Splus like this...
Splus < my.named.pipe
Then, when in grass you could just send the appropriate Splus commands down the pipe (you are at a shell prompt after all). Something like this might work...
grassprompt% echo 'openlook()' > my.named.pipe
grassprompt% echo 'xxx <<- scan()' > my.named.pipe
..... then cat your dataset down the pipe, with a blank line at the end
grassprompt% echo 'hist(xxx)' > my.named.pipe
Its just an idea. I haven't tried it, but it should work in principle.
Something else to check out may be 'Splus INTERFACE' which claims to be able to call S functions from other programming languages.
