[GRASS-user] v.class.mlR Error

[Jamille Haarloo]

I see. That was one of the big problems then. I knew it used R-resources
but wasn't sure the software itself was required. Must have overlooked it
in the documentation and other user- topics as I was reading about the
module.

Now I have R-3.5, but still get an error:
