[MUSIC PLAYING] DAVID MALAN: Hello, world,
this is CS50's Introduction to Programming with R, a popular
language for statistical computing and graphics and data
science and other domains. My name is David Malan. CARTER ZENKE: And my
name is Carter Zenke. DAVID MALAN: Where as CS50,
otherwise known as CS50x focuses on computer science and
programming more generally, this course, CS50R is entirely focused on R. You can
take CS50R before CS50X, during CS50X, or after CS50X. CARTER ZENKE: In this
course, we'll first explore how to represent data
in this language called R, learn our structures for data
called vectors and data frames. We'll then graduate
to transforming data, in particular, filtering
these things called logical expressions that you can use to
analyze subsets of data that you have. We'll consider how to transform
our data using functions and loops, and we'll use paradigms
like functional programming. From there, we'll stand
on the shoulders of those who have written R code before us. All in the pursuit of tidying our
data and making it easier to analyze. Then, once our data is tidy, we are
able to visualize it more easily too. Toward the end of the course,
we'll test our programs to ensure they behave as we intend. And once they do, we'll package them up. This course then will take
you from nothing about R to sharing your knowledge
of R with the world. We're excited to see what you'll create. This is CS50's Introduction
to Programming with R.
