R Essentials Primer for Data Science is a quick-start style, light hands-on course that takes students currently working with Excel (or SAS or another data tool) for numerical analysis and helps them to get started using more powerful Open Source environments including the R programming language. R is a functional programming environment employed by many data analysts and data scientists, easily accessible to non-programmers and naturally extending a skill set that is common to data analysts and data scientists. It's the perfect tool for when the one has a statistical, numerical, or probabilities-based problem based on real data and they've pushed those tools past their limits.
In this course we present common scenarios that are encountered in analysis and present practical solutions. Some attention is paid to data science theory including AI grouping theory. A discussion of using R with libraries are included and prepares the user for using Spark/R (and SparklyR).
NOTE: For deeper hands-on coverage or R Programming for Data Science please consider TT6683 JumpStart Hands-On R Programming for Data Science & Analytics, a variation of this course with more advanced hands-on and concepts.
This course is approximately 40% hands-on lab to 60% lecture ratio, combining engaging lecture, demos, group activities and discussions with light machine-based practical programming labs and exercises. 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.
Students will explore:
- Moving from Excel to R
- R Basics
- Reading and Writing Files
- Multiple Dimensions
- Overview of R in Data Science
