SublimeREPL Unable to Find R - r

Question

Okay, this is driving my crazy. I had set this up before, deleted Sublime Text, and now I can't remember what the right configuration was.
Very simple: I'm running R through SublimeREPL and need to point the REPL to where R is installed.
I followed the directions at http://sublimerepl.readthedocs.org/en/latest/, which say to go into the user-defined REPL settings and add this:
{
...
"default_extend_env": {"PATH": "{PATH}:/home/myusername/bin"}
...
}
where the path points to the right directory. I tried replacing it with
{
...
"default_extend_env": {"PATH": "C:/Program Files/R/R-3.0.2/bin"}
...
}
and it's still unable to find R, plus now it's giving me the error:
Error trying to parse settings: Expected value in Packages\User\SublimeREPL.sublime- settings:2:2
I know this is an easy fix. Can anybody point out what I'm doing wrong here?
*I'm using Sublime Text 3. I previously had this working, but on Sublime Text 2.
I've been to http://tomschenkjr.net/using-sublime-text-2-for-r/ and the piece where he mentions "pointing SublimeREPL at R" ... he doesn't include the actual code, as far as I can see
I've also seen this thread Error 2 The system cannot find the file specified in Sublime Text 2, Windows 8, but I had it working before and didn't have to do anything along those lines

Answer 1

Go to Preferences -> Browse Packages... and create a directory tree User/SublimeREPL/config/R. In that directory, create a new file named Main.sublime-menu with the following contents:
[
{
"id": "tools",
"children":
[{
"caption": "SublimeREPL",
"mnemonic": "r",
"id": "SublimeREPL",
"children":
[
{"command": "repl_open",
"caption": "Rterm",
"id": "repl_r",
"mnemonic": "r",
"args": {
"type": "subprocess",
"external_id": "r",
"additional_scopes": ["tex.latex.knitr"],
"encoding": {"windows": "$win_cmd_encoding"},
"soft_quit": "\nquit(save=\"no\")\n",
"cmd": {"windows": ["C:/Program Files/R/R-3.0.2/bin/x64/Rterm.exe", "--ess", "--encoding=$win_cmd_encoding"]},
"cwd": "$file_path",
"extend_env": {"windows": {"PATH": "{PATH}:/C/Program Files/R/R-3.0.2/bin"}},
"cmd_postfix": "\n",
"suppress_echo": {"windows": false},
"syntax": "Packages/R/R.tmLanguage"
}
}
]
}]
}
]
Save the file, and you should now have a Tools -> SublimeREPL -> Rterm menu option. Double-check that the path is the correct one to the Rterm.exe file. On my computer (32-bit XP) it's in the i386 subfolder of bin, so yours may be in bin/x64 or something like that.
I hope this helps, let me know if you still have issues.

Answer 2

I resolved this by adding the location of Rterm.exe to PATH
