Project that illustrates how to create a new ggplot2 geom in R.

Creating a new ggplot2 geom

This project illustrates how to create a new ggplot2 geom in R that allows to visualize hurricane wind fields using the data from The Tropical Cyclone Extended Best Track Dataset. The motivation of this undertaking was to solve the peer-graded assignment of the Building Data Visualization Tools course.

Organization of the Files

The project has the following structure:

• _CODES: Includes two files: ggplot2.R and submitted_geom_hurricane.R. The first one creates two visualizations of the Hurricane Ike and the latter was the submitted code for the peer-graded assignment of the Coursera's course; moreover, this contains roxygen2-style documentation to exemplify how to integrate the new geom into a new R package.
• _GRAPHS: Contains the plots created by ggplot2.R code in order to demonstrate how the new geom works: Ike_path.png and submitted_image.png.
• _RESOURCES: Includes all the resources that I used during the creation process of the new geom.
• _TEXTS: Consists of all my personal notes that I considered relevant for this task.

Sample images using the new geom

As stated above, the two images created by the geom are the following:

Whole path of the Hurricane Ike at 18:00 UTC during each observed day

Hurricane Ike at latitude 25.8

To-do list

• roxygen2-style documentation needs to include import statements.
• Example must use require instead of ::.
