Project Description
Sepsis is a deadly illness that accounts for a large portion of in-hospital deaths. It occurs when a person's organs shut down in response to a severe infection. This public health problem is a major target for research, and hospital records can help us investigate the problem. In this R project, you will identify hospital patients with severe infection using medical record data.
To successfully complete this project you should have some experience with the
package data.table, including using the := operator, grouping aggregations
with by, and understanding how to use the shift function.
You can learn about data.table in the Data Manipulation in R with data.table course.
