Upon further analysis, it seems that multiple of the categories, e.g. Age, are expected by the mutate function to be integers but are instead characters. Does that seem right? Again, I am able to load the app, and within the "Home" menu, the "Goal Contributions" and "Wage" visualizations are working properly. All other buttons/menus result in errors, e.g. the following when I click on "Squad Analysis" > "General:"
"Warning: Error in dplyr::filter: ℹ In argument: `Name %in% reactindex`.
Caused by error in `dplyr::filter()`:
ℹ In argument: `between(Age, input$squad_age[1], input$squad_age[2])`.
Caused by error in `between()`:
! Can't combine `x` <character> and `left` <integer>."
