Having an R console within QGIS would be incredibly useful! I've been copying and pasting between R and QGIS (keeping the WKT field correctly formatted) using read.table, which works well, too. W.r.t. sp vs. sf, seems like sf is the future for R spatial objects? Any thoughts on this?
Crowdfunding definitely seems like the way forward - which platforms have been used for this kind of project in the past?
