Excellent, I'm glad to hear it. The whole Rpy, Numpy, R, and QGIS 
install process is not as easy as I'd like it to be, so it's good to 
hear that some are getting it to play nicely!

Well it's a bit of both: PyQGIS and RPy use python dicts to store 
attribute data etc., and at some point between reading the attributes 
from QGIS and converting to R the fields get randomised (python dicts 
store key-value pairs in random order to speed retrieval). So it's 
nothing to do with R. I am going to have a look at this today, because 
in the past I have been able to overcome this problem. Thanks for 
reminding me ;-)

This is very nice to hear! I'm hoping to do the same here, so let me 
know about any and all bugs you find while testing, and I'd love to hear 
how your course goes and what content you end up using.

Cheers,


Carson
