About the series

This is an intermediate-level series on R on data manipulation in R, focusing on methods for merging and reshaping data. It will offer both base-R and tidyverse solutions. The series assumes some prior exposure to base R (such as through the prior series, A Slower Introduction to R).

The series will draw on data examples from the health sciences (including public health and medicine). 

Each session (scheduled for 1.5 hours, but we may finish earlier on occasion) will involve short mini lectures, interspersed with hands-on exercises.

Registration for each session requires UCSF MyAccess credentials.

The CLE for this series is available here. 

About this session

Each session is titled in the form of a "How can I..." question. This second session is titled "How can I merge or reshape data?" and will cover:

• merging data using tidyverse or base R
• reshaping data using tidyverse or base R

Participants are strongly encouraged to review the prior session.
