Installing R, RStudio and IPython notebook with the R kernel
============================================================

Install R
---------

Download and install the appropriate version for your operating system
from http://archive.linux.duke.edu/cran/

Install RStudio
---------------

Download and install the appropriate version for your operating system
from https://www.rstudio.com/products/rstudio/download/

Install Jupyter
---------------

Download and install the appropriate version for your operating system
from http://continuum.io/downloads

Install the R kernel for Jupyter
--------------------------------

This is the most complex step and you might need a little help from a
programmer friend to decipher the instructions.

Follow the instructions for your operating system at
https://github.com/IRkernel/IRkernel

Some people rerpot issues with the OS X installation - if you run into
problems, see if `this
page <http://www.michaelpacer.com/maths/r-kernel-for-ipython-notebook>`__
helps.


Installing R Graphics packages
----------------------------------------

.. code:: python

    # from https://gist.github.com/stevenworthington/3178163
    ipak <- function(pkg){
        new.pkg <- pkg[!(pkg %in% installed.packages()[, "Package"])]
        if (length(new.pkg)) 
            install.packages(new.pkg, dependencies = TRUE, repos = "http://cran.r-project.org")
        sapply(pkg, require, character.only = TRUE)
    }
     
    # usage
    packages <- c("ggplot2",  "gplots", "lattice", "plyr", "reshape2",
                  "RColorBrewer", "grid", "gridExtra", "igraph", "igraphdata")
    suppressMessages(ipak(packages))

Check
-----

If everything went well, you should be able to start the Jupyter
notebook from the launhcer (see icon below). Select Launch for the
IPython Notebook (same as Jupyter notebook). The **New** menu on the
right should show both Python and R options.

.. code:: python

    from IPython.display import Image
    Image(filename='launcher.png')
