Don't undersell yourself... these would be very valuable contributions!<br>

I've (very roughly) looked into this, and I also believe it should be<br>
possible to directly create R data frames from QGIS layers. Then we'd<br>
just need to add a "R console" to QGIS, and boom! Awesome spatial<br>
statistical analysis tool directly within QGIS!<br>
