Welcome, and thanks for posting here.

That is from R, and RInside needs to find R.

Setting R_HOME helps. | Basically the reason I need to do this: I've put together a spatial | simulation tool which is hacked together using various components of Qt, | QGIS and GDAL, and calls various R packages via RInside for some | operations. I need to control the R version to keep everything working | properly. I strongly recommend you get the Qt-based example working first, and then expand from here. | Very much appreciate your suggestions - hoping someone has experienced a | similar problem. Sure. Which is why we add a minimal working example to the package.
