Classify Suspected Infection in Patients

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.
