From the developer:
NppToR is an open source program that aims to extend the functionality of code passing to the Notepad code editor. In addition to passing to the R gui, NppToR provides optional passing to a PuTTY window for passing to an R instance a remote machine. It also provides support for batch execution, with a monitor for longer running scripts.
