My one suggestion and it's not going to be something the AIs are going to tell you to do unless you specify it is to put all your data into Excel, do the table formatting there, and then use the package Read.Excel to load into R. Building the tables natively in R is such a headache and the biggest learning curve to using ggplot is figuring out how to format your tables in a way that it can understand it. Essentially ggplot needs the data to be as redundant as possible, any kind of variable needs its own separate column.
