Tutorial for learning rspark

rspark-tutorial

rspark-tutorial provides content illustrating the use of rspark, a Docker-based computing environment. rspark runs R, RStudio, PostgreSQL, Hadoop, Hive, and Spark in containers on your local computer (or optionally on AWS). The content covers a range of topics including many aspects of the tidyverse, machine learning using Spark, etc.

This tutorial is meant to run in conjunction with rspark-docker, which contains images of the rspark components. The steps for installing and launching the rspark-docker containers is given here:

Downloading the `rspark-tutorial content

To get access to the tutorial content within rsaprk-docker, do the following:

1. Make sure git is installed and up to date. This step should have been done when you cloned rspark-docker, but from the command line you can run:

git version

Compare the returned version with the current version. See the directions in the rspark-docker README for installing or updating, if necessary.

2. Issue the following command in a terminal to clone rspark-tutorial:

git clone https://github.com/jharner/rspark-tutorial.git

This will create a directory (folder) in your home directory by default containing the local git repo of rspark-tutorial. If you prefer installing rspark-tutorial in another directory, cd there first.

Uploading the rspark-tutorial content to rspark-docker

Assuming that rspark-docker has been started and that you have logged into the RStudio container:

1. Zip the rspark-tutorial folder on your local computer.

2. Click on the Files tab in the RStudio container and then click the Upload menu item. Navigate to the zipped version of rspark-tutorial and upload.

3. Execute the .Rmd files in the various modules/sections to generate R notebooks or R markdown output files.

Once you have cloned rspark-tutorial, you will be able to pull updates by issuing the following command from within the rspark-tutorial directory (folder):

cd rspark-docker
git pull origin master

The git pulls will keep your tutorial up to date.
