Load the package nycflights13 with library(nycflights13). If you are on running R Studio locally, you must install this package before you can use it!

# install.packages("nycflights13")
library(nycflights13)
library(ggplot2)
library(dplyr)

data(flights)
data(airports)
data(airlines)

Question 2

The dataset `airlines` contains the full name of the carrier (examine it!). Join the dataset with the flights dataset so all of the information in `flights` is retained. Using the merged dataset, which carrier (`name`) has the longest average departure delay? Which has the shortest?

Solutions

Expert Solution

install.packages("nycflights13")
library(nycflights13)
library(ggplot2)
library(dplyr)

data(flights)
data(airports)
data(airlines)

flights = merge(flights,airlines,by= "carrier", all.x=TRUE)

flights[which.max(flights$dep_delay),]
flights[which.min(flights$dep_delay),]

longest is for

Hawaiian Airlines Inc.

shorted is for

JetBlue Airways
