The code is quite long and complex, but I’ll break it down step by step. First, we need to convert your data from a wide format to a long format using pivot_longer. This is because the ggballoonplot function requires a long-format dataset. BD_database %>% select(-c(ID.P, ID.S)) %>% pivot_longer(cols = -AC.TYPE) This will convert your data into a long format with three columns: name, value, and AC.TYPE. Next, we need to convert the value column from TRUE/FALSE to 1/0.
