Many people, including myself, might not like editing .r (source) files in R itself. Therefore I present you a very ingenious way of avoiding this.
“NppToR provides R language syntax highlighting, code folding, and auto-completion to Notepad++. In addition, it provides Rgui style code passing between Notepad++ and the Rgui.”
To use NppToR the first step is to download and install R. Secondly, we dowload and install notepad++. Finally, we download and install NppToR.
Open NppToR by clicking on 
. In the settings window we can see/edit which hot-keys to use and adjust a few thing.
An .r file in notepadd++ now look like

Passing it to R ( F8 (lines), ^F8 (file) ) results in the following
nppToR code passing
My friend Alexander, pointed out that writing R code is even easier (and more fancy) when editing in Komodo (in combination with SciViews-K). I may come back to that later!
An important detail!!! The settings ter is referring to is not the N++ settings menu, but the nppToR settings menu. For me it’s found by right clicking on the tray icon in the bottom right.
I have Notepad++ and NppToR installed. Let’s say I have an R session open which has all my stuff in it, then I open Notepad++ and my code file. I hit “F8” and it opens a new R session, pasting the code in. All subsequent “F8″‘s will paste the code into that session also.
How do I get the code to paste into that first R session I already had open?
I have no idea. Maybe you could have a look at this forum. I will investigate too.
Maybe you could play with the “R cmd line parameters” under settings?
I read somewhere else that it might be a Windows 7 issue, but no one has issued a fix or anything.
I know that the question was asked over 3 years ago, but perhaps someone will come across this post looking for the answer.
As tersmitten hinted, add “–sdi” to the command line parameters.
NppToR will then send R code to the active R window
Do not open the R session. AFter you install NppToR you will have NppToR app in your windows. Click on that. it will open NPP. Write some R code and hit F8. It should open R session and will run the code that you trying to run.
