Agenda 6 • Anaconda and “R Essentials” • Conda: package and environment manager • Jupyter: collaborative notebooks • Bokeh: interactive data visualizations

CONDA, ANACONDA & R ESSENTIALS Introduction

8 Conda • Package and environment manager • Language angnostic (Python, R, Java…) • Cross-platform (Windows, OS X, Linux) $ conda install python=2.7 $ conda install pandas $ conda install -c r r $ conda install mongodb

9 Conda • Open source: BSD license • Docs: http://conda.pydata.org/docs/ • GH: https://github.com/conda

10 Conda vs Anaconda vs Miniconda vs R Essentials • Conda: package manager • Anaconda: Python + Conda + packages • Miniconda: Python + Conda • R Essentials: R + R packages

11 Language agnostic Python packages handles environments ! natively virtualenv installs binaries compiles from source general purpose ! envs python! envs Conda Pip

12 Conda + pip $ conda install pip $ pip install foo Conda skeleton pip $ conda skeleton pip foo $ conda build foo/

13 Why Conda? • Python with compiled, platform-dependent C, C++, or Fortran code • Seen this message too many times:“Storing debug log for failure in /.pip/pip.log” • Multi-language Data Science Projects

14 Anaconda Cloud ~ Github for binary packages

15 Anaconda Cloud $ conda build conda.recipe/ $ conda server upload my_foo_pkg $ conda install -c chdoig my_foo_pkg

16 Anaconda for R users $ conda install -c r r-foo

17 Mirror CRAN packages $ conda skeleton cran ldavis ! $ conda build r-ldavis/ ! $ conda server upload my_r_pkg ! $ conda install -c chdoig my_r_pkg

18 Conda environments name: myenv channels: - chdoig - r - foo dependecies: - python=2.7 - r - r-ldavis - pandas - mongodb - spark=1.5 - pip - pip: - flask-migrate - bar=1.4 environment.yml $ conda env create $ source activate myenv $ conda env export -n freeze.yml Create and activate Freeze versions Upload to anaconda.org $ conda server upload my_foo_env.yml $ conda env create chdoig/my_foo_env.yml

19 Conda auto env cdoig:~$ cd pygotham-topic-modeling/ discarding /anaconda/bin from PATH prepending /anaconda/envs/pygotham-topic/bin to PATH (pygotham-topic)cdoig:~/pygotham-topic-modeling$ https://github.com/chdoig/conda-auto-env

20 "R essentials" comes with IRKernel and over 80 of the most used R packages for data science like dplyr, shiny, ggplot2, tidyr, caret and nnet. $ conda install -c r r-essentials $ conda config --add channels r or $ conda install r-essentials R Essentials

21 or, alternatively, create an environment to isolate your "R essentials" packages from others: ! $ conda create -n r-essentials -c r r-essentials R Essentials environment

22 $ conda metapackage custom-r-bundle 0.1.0 --dependencies r-irkernel jupyter r-ggplot2 r-dplyr --summary "My custom R bundle” ! Custom metapackage to share

JUPYTER Introduction

24 http://jupyter.org/ https://try.jupyter.org/ The Jupyter Notebook is a web application that allows you to create and share documents that contain live code, equations, visualizations and explanatory text.

25 IPython IPython notebook nbviewer tmpnb binder Jupyter https://try.jupyter.org/ http://mybinder.org/

26 ! To start jupyter notebooks, simply run the following command: ! $ jupyter notebook http://nbviewer.ipython.org/github/chdoig/conda-jupyter-irkernel/blob/master/Jupyter%20and%20conda%20for%20R.ipynb
