Having a hard time getting started with Vim-R-plugin

I am trying to install the R-project (f开发者_运维知识库or statistics) plugin for VIM, on my PC (using ubuntu).

I have followed the instruction on the plugin web page

• I have installed the conque shell plug in as well, as requested.
• I have installed the vim-r-plugin

• I have added the 4 needed line to my .vimrc file:

  set nocompatible
  syntax enable
  filetype plugin on
  filetype indent on
  

• I have set my maplocalleader to ,
• I open a .R file
• I try the command, like :,rf, and I get: E492: Not an editor command: ,rf

I don't know really how to trouble shout this problem, or where to find help.

Sorry, my first answer was out of scope.

You needn't : to use mappings. Just hit ,rf

old answer was:

Usually, vim commands can be prefixed with a line range. Here the :, suggests you are indicating a line range.

Valid line ranges might be (not a full list):

• a (single line)
• [a],b (line ranges)
• % (synonym of 1,$)

a and b can be replaced with . (current line), $ (last line), any valid line number, 'x where x is a mark, and any arithmetic combination of them.

But , alone does not seem to be appropriate in front of a command name.
