Event description

Description

In this day-long training, you will learn about R, the premier language for data analysis. We will approach the language from the standpoint of data professionals: database developers, database administrators, and data scientists. We will see how data professionals can translate existing skills with SQL to get started with R. We will also dive into the tidyverse, an opinionated set of libraries which has modernized R development. We will see how to use libraries such as dplyr, tidyr, and purrr to write powerful, set-based code. In addition, we will use ggplot2 to create production-quality data visualizations.

Over the course of the day, we will look at several problem domains. For database administrators, areas of note will include visualizing SQL Server data, predicting error occurrences, and estimating backup times for new databases. We will also look at areas of general interest, including analysis of open source data sets.

No experience with R is necessary. The only requirements are a laptop and an interest in leveling up your data professional skillset.

Intended Audience

  • Database developers looking to tame unruly data
  • Database administrators with an interest in visualizing SQL Server metrics
  • Data analysts and budding data scientists looking for an overview of the R landscape
  • Business intelligence professionals needing a powerful language to cleanse and analyze data efficiently

Contents

  • Ensure laptops are ready to go

Module 1 -- Basics of R

  • What is R?
  • Basic mechanics of R
  • Embracing functional programming in R
  • Connecting to SQL Server with R
  • Identifying missing values, outliers, and obvious errors

Module 2 -- Intro to the Tidyverse

  • What is the Tidyverse?
  • Tidyverse principles

    • Analyzing Backup Times

Course Objectives

Upon completion of this course, attendees will be able to:

  • Perform basic data analysis with the R programming language
  • Take advantage of R functions and libraries to clean up dirty data
  • Build a notebook using Jupyter Notebooks
  • Create data visualizations with ggplot2

Pre-Requisites

No experience with R is necessary, though it would be helpful. Please bring a laptop to follow along with exercises and get the most out of this course.
