    Things to Install
    # How to use Neovim or VIM as an R IDE
    Note: This tutorial is written for Linux based systems.

    ## Requirements

    R >= 3.0.0
    http://www.r-project.org/
    Either use your package manager or compile from source.
    ### R >= 3.0.0
    To install the latest version of R please flollow the download and install instructions at [https://cloud.r-project.org/](https://cloud.r-project.org/)

    ### Neovim >= 0.2.0
    [Neovim](https://neovim.io/) (nvim) is the continuation and extension of Vim editor with the aim to keep the good parts of Vim and add more features. In this tutorial I will be using Neovim (nvim), however, most of the steps are equally applicable to Vim also. Please follow download and installation instructions on nvim's GitHub wiki [https://github.com/neovim/neovim/wiki/Installing-Neovim](https://github.com/neovim/neovim/wiki/Installing-Neovim).

    Vim >= 8.1
    https://github.com/vim/vim
    **OR**

    ### Vim >= 8.1
    [Vim](https://github.com/vim/vim) usually comes installed in most of the Linux based operating system. However, it may not be the latest one. Therefore, to install the latest version please download and install it from Vim's GitHub repository as mentioned below or a method that is more confortable to you.

    To compile and install the latest version of VIM.
    ```
    git clone https://github.com/vim/vim.git
    make -C vim/
    sudo make install -C vim/
    ```

    ### Plugin Manager
    There are more than one plugin manager's available for Vim that can be used to install the required plugins. In this tutorial I will be using [vim-plug](https://github.com/junegunn/vim-plug) pluggin manager.

    Plugins
    1. Nvim-R https://github.com/jalvesaq/Nvim-R
    2. Nerd Tree https://github.com/preservim/nerdtree
    3. Lightline https://github.com/itchyny/lightline.vim
    ### Plugins
    In the end below are the plugins that we would need to convert Vim editor into a fully functional IDE for R.

    1. Nvim-R: [https://github.com/jalvesaq/Nvim-R](https://github.com/jalvesaq/Nvim-R)
    * Nvim-R is the main plugin that will add the functionality to execute R code from within the Vim editor.
    1. Ncm-R: [https://github.com/gaalcaras/ncm-R](https://github.com/gaalcaras/ncm-R)
    * Ncm-R adds synchronous auto completion features for R.
    1. Nerd Tree: [https://github.com/preservim/nerdtree](https://github.com/preservim/nerdtree)
    * Nerd Tree will be used to toggle file explorer in the side panel.

    2. Make sure that you have VIM >= 8.1 is installed.
    3. Install the Vim-Plug plugin manager.

    ## Procedure

    curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

    1. Make sure that you have `R >=3.0.0` is installed.

    ```

    4. Install the required plugins.

    First, create a .vimrc file then add:


    ```
    " Specify a directory for plugins
    " - Avoid using standard Vim directory names like 'plugin'
    call plug#begin('~/.vim/plugged')

    " List of plugins.
    " Make sure you use single quotes

    " Shorthand notation

    Plug 'ncm2/ncm2'
    Plug 'roxma/nvim-yarp'
    Plug 'gaalcaras/ncm-R'
    Plug 'preservim/nerdtree'
    Plug 'itchyny/lightline.vim'

    " IMPORTANT: :help Ncm2PopupOpen for more information
    set completeopt=noinsert,menuone,noselect
    ```

    To the .vimrc file that we have created above. Add the following lines.

    5. Update and add more features to the `init.vim` file.

    ```
