Introduction to Data Analysis Using R

Oct 5, 2023

Online venue
University of Iowa, Iowa City, IA 52242

1. Overview

R is a popular programming language for statistical computing and graphics. This 2-day workshop focuses on the basic concepts and features of R that will serve as building blocks for data analysis tasks. The workshop is taught using RStudio in the Interactive Data Analytics Service (IDAS).

2. Prerequisites

No experience with R or RStudio is required. A basic understanding of general statistical concepts, as typically taught in the first college-level statistics course, may be helpful for attendees to follow the sections on statistics. (See the workshop agenda below.)

3. Eligibility

This workshop is available to current University of Iowa faculty, staff, and students, who are employed by the University or enrolled in a class at the University at the time of the workshop.
