Using R now is closer and more similar to just using Python #rstats #python

Some developments- (this should be interesting to Microsoft that is basically leading player in Enterprise Solutions in R after completely acquiring Revolution R and RStudio being headed by another Microsoft alum)

  1. you can install R using miniconda http://continuum.io/conda-for-R Screenshot from 2015-09-16 13:07:26
  2. you can run R using Jupyter notebooks

R Essentials” setup

The Anaconda team has created an “R Essentials” bundle with the IRKernel and over 80 of the most used R packages for data science, including dplyr, shiny, ggplot2, tidyr,caret and nnet.

Downloading “R Essentials” requires conda. Miniconda includes conda, Python, and a few other necessary packages, while Anaconda includes all this and over 200 of the most popularPython packages for science, math, engineering, and data analysis. Users may install all of Anaconda at once, or they may install Miniconda at first and then use conda to install any other packages they need, including any of the packages in Anaconda.

Once you have conda, you may install “R Essentials” into the current environment:

conda install -c r r-essentials
Bash

or create a new environment just for “R essentials”:

conda create -n my-r-env -c r r-essentials
Bash

Jupyter

Jupyter provides a great notebook interface to write your analysis and share it with your peers. Open a shell and run this command to start the Jupyter notebook interface in your browser:

jupyter notebook
Bash

Start a new R notebook:

create an R notebook with jupyter

You can immediately write and run R code in the notebook cells.

  1. Running R from within Python – yeah!

Step 1: install miniConda

Step 2: open an OS terminal window:

conda install -c r ipython-notebook r-irkernel
ipython notebook

Using R Within the IPython Notebok

Using the rmagic extension, users can run R code from within the IPython Notebook. This example Notebook demonstrates this capability.
