I have been attempting to use CalendR to generate a color-coded calendar. I keep getting an error message that states unused arguments. The only thing I can think why is because I am using multiple packages (dplyr and lubridate) as well OR because the version CalendR was developed under does not align with the version of R I am using. I am at a loss.

school_year <- "2024-25"
start_date <- "2024-08-01"
end_date <- "2025-06-30" 


calendar <- calendR(
  start_date = start_date,
  end_date = end_date,
  weeknames = c("Mon" ,"Tue", "Wed", "Thu", "Fri", "Sat", "Sun"),
  title = paste(school_year, "Bus Projections", sep = " "),
  subtitle = paste("Projected # of Buses Needed Each Day. As of ", Sys.Date(), ".", sep=""),
  special.days = calendar_data,
  special.col = c("#17d100",
              "#84ef77",
              "yellow",
              "dark orange",
              "red",
              "darkred",
              "grey"),
  months.col = "white",
  mbg.col = "black",
  legend.pos = "top",
  orientation = "portrait",
  pdf = TRUE,
  doc_name = paste(school_year, "Bus Projections", Sys.Date()))`

I’ve tried using start_date= “2024-08-01” except for start_date=start_date and the same for end_date.

I’ve also tried saving everything and using only CalendR (no library of dplyr or lubridate).
