S04E14: R for Data Science - Chapter 5.6: summarize, some more
Today we will continue to investigate the summarize() function. Together with group_by(), this function is extremely useful to produce summary statistics of your data by group.

S04E12: R for Data Science - Chapter 5.5: mutate
Today we will cover the mutate() function to create new columns in dataframes. While this function itself is simple enough, we will get to see some interesting data manipulation techniques and operators such as those for integer division and remainder.

S04E10 and S04E11: R for Data Science - Chapters 5.3 and 5.4
In these two sessions of Code Club, we look at sorting dataframes with arrange() and filtering rows of a dataframe based on certain conditions with filter().

S04E09: R for Data Science - Chapter 5.1 - 5.2
This chapter covers the manipulation of rectangular data (data frames, think data from spreadsheets) with the dplyr package that is part of the tidyverse. We’ll learn about data frames & tibbles, R variable types, comparison and logical operators, and missing values (NAs) in addition to the first of the core dplyr functions: filter()

S04E08: R for Data Science - Chapters 4, 6, and 8
In this first session of Code Club for Fall ‘22, we will continue working our way through the book R for Data Science. Today, we’ll look at three very short chapters on some R and RStudio basics.

S04E01: R for Data Science - Chapter 1
We will introduce a new season of Code Club, in which we’ll do things a little differently than before: we are going to work our way through a book: R for Data Science. Today, we’ll look at the first, introductory chapter of the book.

Session S03E12: Incorporating your own functions into loops
In this session of Code Club, we’ll see how putting your own functions into loops prevents repeating yourself even more.

Session S03E12: Incorporating your own functions into loops
Session S03E11: Writing your own Functions
In this session of Code Club, we’ll look at how to avoid repeating yourself in another way by writing your own functions.

Session S03E11: Writing your own Functions
Session S03E10: Functional Programming With purrr::map() Functions
In this session of Code Club, we’ll consider some functions from the purrr package, which can be used as efficient alternatives to for loops and the apply() functions we explored in the previous session.
