This course, The Comprehensive Statistics and Data Science with R Course, is mostly based on the authoritative documentation in the online “An Introduction to R” manual produced with each new R release by the Comprehensive R Archive Network (CRAN) development core team. These are the people who actually write, test, produce and release the R code to the general public by way of the CRAN mirrors. It is a rich and detailed 10-session course which covers much of the content in the contemporary 105-page CRAN manual. The ten sessions follow the outline in the An Introduction to R online manual and specifically instruct with respect to the following user topics:
1. Introduction to R; Inputting data into R
2. Simple manipulation of numbers and vectors
3. Objects, their modes and attributes
4. Arrays and matrices
5. Lists and data frames
6. Writing user-defined functions
7. Working with R as a statistical environment
8. Statistical models and formulae; ANOVA and regression
9. GLMs and GAMs
10. Creating statistical and other visualizations with R
It is a comprehensive and decidedly “hands-on” course. You are taught how to actually use R and R script to create everything that you see on-screen in the course videos. Everything is included with the course materials: all software; slides; R scripts; data sets; exercises and solutions; in fact, everything that you see utilized in any of the 200+ course videos are included with the downloadable course materials.
The course is structured for both the novice R user, as well as for the more experienced R user who seeks a refresher course in the benefits, tools and capabilities that exist in R as a software suite appropriate for statistical analysis and manipulation. The first half of the course is suited for novice R users and guides one through “hands-on” practice to master the input and output of data, as well as all of the major and important objects and data structures that are used within the R environment. The second half of the course is a detailed “hands-on” transcript for using R for statistical analysis including detailed data-driven examples of ANOVA, regression, and generalized linear and additive models. Finally, the course concludes with a multitude of “hands-on” instructional videos on how to create elegant and elaborate statistical (and other) graphics visualizations using both the base and gglot visualization packages in R.
The course is very useful for any quantitative analysis professional who wishes to “come up to speed” on the use of R quickly. It would also be useful for any graduate student or college or university faculty member who also seeks to master these data analysis skills using the popular R package.
