R Programming for Data Science & Analytics

R is a functional programming environment for business analysts and data scientists. It's a language that many non-programmers can easily work with, naturally extending a skill set that is common to high-end Excel users. It's the perfect tool for when the analyst has a statistical, numerical, or probabilities-based problem based on real data and they've pushed Excel past its limits. Introduction to R Programming for Data Science & Analytics is a comprehensive hands-on course that presents common scenarios encountered in analysis and present practical solutions. In this course, special attention is paid to data science theory including AI grouping theory. A discussion of using R with AI libraries like Madlib are included.

Learning Objectives

This course provides indoctrination in the practical use of the umbrella of technologies that are on the leading edge of data science development focused on R and related tools. Working in a hands-on learning environment, led by our expert practitioner, students will learn R and its ecosystem, and where it’s a better a tool than Excel.

This course is approximately 50% hands-on, combining expert lecture, real-world demonstrations and group discussions with machine-based practical labs and exercises. Our engaging instructors and mentors are highly experienced practitioners who bring years of current "on-the-job" experience into every classroom. Working in a hands-on learning environment, guided by our expert team, attendees will learn about and explore:

  • R Language and Mathematics
  • How to work with R Vectors
  • How to read and write data from files, and how to categorize data in factors
  • How to work with Dates and perform Date math
  • How to work with multiple dimensions and DataFrame essentials
  • Essential Data Science and how to use R with it
  • Visualization in R
  • How R can be used in Spark (Optional / Overview)
