[Qgis-user] manageR update

Borys,

Not a cyborg, but I did give up sleep about a month ago ;)

Thanks!

Hmm, I don't use GRASS a lot, so I didn't implement this, but now that you
mention it, it's probably a good idea. Unfortunately (and again, in this
case I'm stuck with OGR drivers here for now) GRASS layers are read only
AFAIK. So maybe I'll set it up so that you can read them in, and then
export them to one of the other org formats...?

This is my dream as well. I don't know C though, so I don't know how I
would write a function to convert say a QgsVectorLayer to a sp
Spatial*DataFrame? Anyone wanna give it a go?

I think this is a very good idea, and I will implement this later tonight.
Look for an updated manageR with an added button to load only attributes.

Great! The more the merrier. This is a cool project, and I think it can
really set QGIS apart as an all-in-one spatial analysis solution!
