I’ve taught the following three courses for Data Matters a week-long series of one and two-day courses aimed at students and professionals in business, research, and government from 2016-2023. The material is open to anyone. Feel free to use these materials for educational purpose!
This course introduces the powerful and popular R
statistical software
through the RStudio integrated development environment. R
is fully
developed programming language and one of the major platforms for doing
data science. This course covers frequently used data structures,
importing raw data, common data manipulations, summary statistics, and
data visualizations through the suite of packages called the
tidyverse
.
The course provides a modern introduction to the R
through the
extremely popular suite of packages called the tidyverse
. A rough

the efficiency of your R
programs. These techniques include the use of
loops and vectorized functions to avoid repeated sections of code. To
really take R
programs to the next level, we’ll see how to write
custom functions that will help to streamline code.
The course provides a brief overview of R
data structures followed by
the following topics:
