R Programming Essentials 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 hands-on course that presents common scenarios encountered in analysis and present practical solutions. 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, you’ll learn R and its ecosystem, and where it’s a better a tool than Excel.
