This repository contains the third lesson for our series on GIS work in R. We'll focus on geoprocessing, which is a set of techniques for (a) modifying the geometric data we are working with or (b) using our geometric data as a starting point for modifying our attributes.
At the end of this lesson, participants should be able to:
- Perform common geoprocessing techniques in
R, including identifying centroids, intersecting and clipping features, and dissolving features
- The
notebook/directory contains the materials for this lesson.
If you participated in the first session, there is no new software for today. However, the packages we'll need for today can be installed if you have not already done so using:
install.packages(c("tidyverse", "here", "knitr",
"nngeo", "mapview", "rmarkdown",
"sf", "tigris", "usethis"))You can download this lesson to your Desktop easily using usethis:
usethis::use_course("https://github.com/slu-dss/gis-04/archive/master.zip")By using usethis::use_course, all of the lesson materials will be downloaded to your computer, automatically extracted, and saved to your desktop. You can then open the .Rproj file to get started.
Please note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms.
This seminar series introduces the basics of working with spatial data in R, including data wrangling and basic map production.
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.
