The sfo package summarizes the monthly air passengers and landings at San Francisco International Airport (SFO) between 2005 and 2022. Data source: San Francisco data portal - DataSF API
Installation
Install the stable version from CRAN:
install.packages("sfo")or install the development version from Github:
# install.packages("devtools")
devtools::install_github("RamiKrispin/sfo", ref = "main")Datasets
The sfo package provides the following two datasets:
-
sfo_passengers- air traffic passengers statistics -
sfo_stats- air traffic landings statistics
More information about the datasets is available in the following vignette.
Examples
The sfo_passengers dataset provides monthly summary of the number of passengers in SFO airport by different categories (such as terminal, geo, type, etc.):

The total number of passengers in most recent month by activity_type_code and geo_region:
library(dplyr)
sfo_passengers %>%
filter(activity_period == max(activity_period)) %>%
group_by(activity_type_code, geo_region) %>%
summarise(total = sum(passenger_count), .groups = "drop")
#> # A tibble: 19 × 3
#> activity_type_code geo_region total
#> <chr> <chr> <int>
#> 1 Deplaned Asia 147461
#> 2 Deplaned Australia / Oceania 45950
#> 3 Deplaned Canada 53237
#> 4 Deplaned Central America 12749
#> 5 Deplaned Europe 124301
#> 6 Deplaned Mexico 64121
#> 7 Deplaned Middle East 28921
#> 8 Deplaned US 1353634
#> 9 Enplaned Asia 166684
#> 10 Enplaned Australia / Oceania 44286

#> 17 Thru / Transit Australia / Oceania 2817
#> 18 Thru / Transit Europe 2496
#> 19 Thru / Transit US 3129The sankey_ly function enables us to plot the distribution of a numeric variable by multiple categorical variables. The following example shows the distribution of the total United Airlines passengers during 2019 by a terminal, travel type (domestic and international), geo, and travel direction (deplaned, enplaned, and transit):
sfo_passengers %>%
filter(operating_airline == "United Airlines",
activity_period >= 201901 & activity_period < 202001) %>%
mutate(terminal = ifelse(terminal == "International", "international", terminal)) %>%
group_by(operating_airline,activity_type_code, geo_summary, geo_region, terminal) %>%
summarise(total = sum(passenger_count), .groups = "drop") %>%
sankey_ly(cat_cols = c("operating_airline", "terminal","geo_summary", "geo_region", "activity_type_code"),
num_col = "total",
title = "Dist. of United Airlines Passengers at SFO During 2019")
Total number of landing
The total number of landings during the most recent month by activity_type_code and aircraft_manufacturer:
sfo_stats %>%
filter(activity_period == 202212,
aircraft_manufacturer != "") %>%
group_by(aircraft_manufacturer) %>%
summarise(total_landing = sum(landing_count),
`.groups` = "drop") %>%
arrange(-total_landing) %>%
plot_ly(labels = ~ aircraft_manufacturer,
values = ~ total_landing) %>%
add_pie(hole = 0.6) %>%
layout(title = "Landing Distribution by Aircraft Manufacturer during Dec 2022")
The following Sankey plot demonstrates the distribution of the number of landing in SFO by region and aircraft type, manufacturer, and body type during Dec 2022:
sfo_stats %>%
filter(activity_period == 202212) %>%
group_by(geo_summary, geo_region, landing_aircraft_type, aircraft_manufacturer, aircraft_body_type) %>%
summarise(total_landing = sum(landing_count),
groups = "drop") %>%
sankey_ly(cat_cols = c("geo_summary", "geo_region",
"landing_aircraft_type",
"aircraft_manufacturer",
"aircraft_body_type"),
num_col = "total_landing",
title = "Landing Summary by Geo Region and Aircraft Type During Dec 2022")
