Data analysis paradigms in the R-tidyverse
Understanding and exploiting the Tidyverse ecosystem for data science
The relationship between tidyverse packages and base R packages can be complicated. And it’s sometimes difficult to see how tidyverse packages relate to each other—let alone use them in concert.
Join expert Rick Scavetta to explore the recurring paradigms in data analysis that the tidyverse ecosystem is well suited to address. Over three hours, you’ll learn to identify these small recurring patterns as you trace the path from raw data to results using real-world examples and a small collection of useful functions. By the time you’re through, you’ll understand the close link between data structure and these functions as well as how they facilitate efficient data analysis that you can apply directly to your own projects.
What you'll learn-and how you can apply it
By the end of this live online course, you’ll understand:
- Tidyverse functions and data analysis paradigms
- The purpose of different packages and how they work in concert
And you’ll be able to:
- Identify recurring themes in data analysis workflows, moving from raw data to completed results in an efficient manner
- Dig deeper into tidyverse packages not covered in the course and understand how they all fit together to build an ecosystem
- Determine what each package is useful for and implement the core functions within each
This training course is for you because...
- You are familiar with base R but lack an overview of the Tidyverse.
- You have existing R scripts that you need to modify.
- You need a more efficient and human-readable way of dealing with complex data problems.
- A basic knowledge of RStudio
- A working knowledge of base R package fundamentals (functions, objects, indexing, and logical expressions)
- Familiarity with the most common data structures in R (vectors, lists, and data frames)
- An RStudio account (You’ll be provided a web-based RStudio cloud instance for the course)
- Take Inferential Statistics Using R (live online training course with Rick Scavetta)
