Change default editor in RStudio to notepad++

Question

I would like to change default editor in RStudio (Windows 7) to notepad++.

I know that I should use

options(editor = "notepad")

and then run, for example:

mean <- edit(mean)

but when I type notepad++ I get this error

options(editor = "notepad++")
mean <- edit(mean)
Error in edit(name, file, title, editor) : 
  unable to run editor 'notepad++'

I Windows I can run notepad++ in console by typing "start notepad++".

I would be very grateful for help!

Ok, it was really simple:

options(editor = "C:/Program Files (x86)/Notepad++/notepad++.exe")

Sorry for the problem.
