Lab 12: A Short Presentation
Three slides: a title, a daily delay table, and a line plot.
Work in a Quarto document. A Quarto
revealjs deck or an R Markdown HTML presentation
(ioslides_presentation or slidy_presentation)
are both fine. Do 12.1 first.
Load packages silently (include = FALSE
or #| include: false). You will need tidyverse
and nycflights13. flights is already 2013.
library(tidyverse)
library(nycflights13)1. Cover
A title slide. YAML title and author are
enough. Add a subtitle if you want.
2. Mean arrival delay by day
A slide that shows the code that computes mean
arr_delay by calendar day from
nycflights13::flights. Use
make_date(year, month, day) (lubridate, loaded with
tidyverse), then group_by(date) and
summarize(). Save the summary tibble. Print it or
head() it so a table appears on the slide.
3. The line plot, no code
A slide that shows a line plot of that daily mean against date. Hide
the code (echo = FALSE). The plot is the slide.
