I would like to run R version 3.4 instead of the current, 3.3.2, and don't really know where to begin.
Web searches left we with little, perhaps, though, because I am not used to working on the Windows 10 platform and don't fully understand how the components in Visual Studio are layered.
I hope this answers your questions.
In the bottom right of the VS console there will most likely stand R 3.3.2, if you click on it, a menu will pop up, allowing you to switch between the different versions available on your machine.
You will see in the bottom right, he is running Microsoft R Open 3.3.2, this is where you click to change versions
