library(rlang)
library(tidyverse)
library(lubridate)
library(nycflights13)

flights_2 <- flights %>% 
  mutate(departure_month = ymd(str_c(year, month, "01", sep = "-"))) %>% 
  group_by(departure_month) %>% 
  summarize(arrival_delay = mean(arr_delay, na.rm = TRUE))
flights_2

chart_func <- function(df, x, y) {
  x <- enexpr(x)
  y <- enexpr(y)

  ggplot(df, aes(!!x, !!y)) + 
    geom_line()

}

chart_func(df = flights_2, x = departure_month, y = arrival_delay)
