  1. Click on the create project icon on the top right of the project list.
  1. Type a name for your project. For instance, "DSX Lab". A Spark service and an object storage will be automatically selected as well as a container with a default name. A container is a directory on the object storage. Click on Create.
  • Click on the add data assets + icon
  • Click on the Add file and select each of the files from the data directory of the downloaded zip: BlocPower_T, CDD-HDD_Features, and HDD_Features

  • Once you are inside the notebook, you need to insert credentials to access the data you uploaded.
  • Click inside the blank cell near the top of the notebook (shown in screen shot below)
  • Click on BlocPower_T.csv on the right side to Insert Credentials

** If you don't see your files click on this icon: **

  • After you add the credentials, rename the variable to be called credentials in code you added, shown below
  • Now you can run each cell to recreate the analysis
  • Follow along each of the following steps:
    • Data cleaning
    • Fitting a linear regression model
    • Conducting k-means clustering

3. Running the Shiny App - Flex Dashboard

  • Open RStudio in Data Science Experience from the left navigation bar
  • Create a new R Markdown Document, select Shiny as the type R Markdown document (note you may be required to download some R packages at this time)
  • Copy the raw R Markdown from here
  • Replace the default content in the new R Markdown file by pasting the code in the file
  • Select lines 21 - 65 and execute (This is a one time set up to install all necessary packages)
  • Click the "Run Document" button to generate the dashboard from the R script
  • Having popup blockers installed may interfere with launching the dashboard
