[GRASS-user] v.class.mlR Error

[Jamille Haarloo]

Dear GRASS GIS community,

I just started working with Grass to try some object-based analysis. I do
not have much experience with programming, but learning bits on the go.
The segmentation test with uspo appears to have been ok, but I am
struggling with the next step. I was suspecting the training vector created
in QGIS wasn't meeting proper standards, but I could not find a
straightforward Grass module for labeling segments/ creating a training set
file.

Hopefully someone can help me out.

Command output:
