Extra Resources

Access Lesson

Initial Package Installation

We use the install.packages function to install modular components of the R ecosystem. For instance, to access lesson materials, we'll use the usethis package. To install it, we run the following function in our console:

install.packages("usethis")

Download Lesson Materials

With the package installed, you you can download this lesson to your Desktop easily using usethis:

usethis::use_course("https://github.com/slu-dss/research-01/archive/master.zip")

or

usethis::use_course("https://bit.ly/2wISdxO")

By using usethis::use_course, all of the lesson materials will be downloaded to your computer, automatically extracted, and saved to your desktop. The research-01-master project should open automatically afterwards.

Install Other Packages for Today

In addition to usethis, there are a couple of other packages we'll need:

install.packages(c("cowsay", "knitr", "rmarkdown"))

Now we're ready to go!

About the SLU DSS

Reproducible Research in R

This seminar is our introductory series of lessons for using R and RStudio with an eye towards reproducibility. We focus on some basic features of R itself, organizing with R projects, loading data using the haven package, crafting R notebooks and using RMarkdown syntax, and using the knitr package. More details are available on our website.

About the SLU Data Science Seminar

The SLU Data Science Seminar (DSS) is a collaborative, interdisciplinary group at Saint Louis University focused on building researchers’ data science skills using open source software. We currently host seminars focused on the programming language R. The SLU DSS is co-organized by Christina Gacia, Ph.D., Kelly Lovejoy, Ph.D., and Christopher Prener, Ph.D.. You can keep up with us here on GitHub, on our website, and on Twitter.
