This R code is used to track patient treatment and infection status. Here’s a breakdown of the steps: Data Collection: The data dsn represents patients’ information, including their treatment dates (date) and whether they received the treatment (instance == 1 or instance == 2). It also stores whether they were infected (type) and when. Filtering Infection Dates: The code then filters these data to only include patients who were infected within a certain timeframe (365 days) after receiving their treatments.

Understanding Stacked Bar Charts in ggplot2 Why do stacked bar charts not match values in tables? In this article, we will explore why stacked bar charts from the ggplot package in R may not accurately represent the values of their corresponding data table. We’ll examine a reproducible example and discuss potential solutions to resolve this issue. What is a Stacked Bar Chart? A stacked bar chart is a visualization technique that displays multiple series of data as separate bars that stack on top of each other.
