Improving Dodging Behavior in Prescription Segment Plots Using Adjacency Matrices
The problem is that the current geom_segment plot is not effectively dodging overlapping segments due to the high density of prescriptions. To improve this, we can use a different approach to group and offset segments. One possible solution is to use an adjacency matrix to identify co-occurring prescriptions within each individual, and then use these groups to dodge overlapping segments. Here’s an updated R code that demonstrates this approach: library(dplyr) library(igraph) # assuming df is the dataframe containing prescription data plot_df <- df %>% filter(!
