library(apexcharter)

apex(economics, aes(date, psavert), type = "line") %>% 
  set_input_selection("selection")


# Default selection at start
apex(economics, aes(date, psavert), type = "line") %>% 
  set_input_selection(
    inputId = "selection", 
    xmin = format_date("1980-01-01"), 
    xmax = format_date("1985-01-01")
