R: How can I subset data and define missing values? Online
About the session
This session will cover:
- subset() and is.na()
- numerical comparisons
- logical objects
- defining missing values
This is part of an introductory workshop series on R. You are welcome to attend even if you unable to attend prior sessions. Please do, however, take a look at content from the prior sessions to ensure that you are caught up.
About the series
A Slower Introduction to R is designed for UCSF researchers who intend to begin using R in their research. The series is intended to be a (relatively) slow-paced introduction to R. It does not assume any prior exposure to R or computer programming. The series has been designed to help learners approach common data-related tasks, and 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.
About the instructor
The instructor, Yea-Hung Chen, PhD, MS, has 10 years of experience teaching R to the UCSF community. He designed and taught UCSF's first-ever R course (Biostat 213) and taught the introductory biostatistics course for UCSF's MS in Global Health program (GHS 207).
