starwarsdb

CRAN status CI by {tic}

starwarsdb provides data from the Star Wars API as a set of relational tables, or as an in-package DuckDB database.

Formats: Metadata, Local Tables, Remote Tables, Data Model (dm), API (rwars)

Installation

You can install starwarsdb from CRAN:

install.packages("starwarsdb")

Or you can install the development version of starwarsdb from GitHub with remotes:

# install.packages("remotes")

remotes::install_github("gadenbuie/starwarsdb")

# For remotes <= 2.1.0
remotes::install_github("gadenbuie/starwarsdb@main")

Star Wars Data

All of the tables are available when you load starwarsdb

library(dplyr)
library(starwarsdb)

or via

data(package = "starwarsdb")

The schema table includes information about the tables that were sourced from SWAPI.

Local Tables

Ask questions, like who flew an X-Wing?

x_wing_pilots <- pilots %>% filter(vehicle == "X-wing")
x_wing_pilots
#> # A tibble: 4 x 2
#>   pilot             vehicle
#>   <chr>             <chr>  
#> 1 Luke Skywalker    X-wing 
#> 2 Biggs Darklighter X-wing 
#> 3 Wedge Antilles    X-wing 
#> 4 Jek Tono Porkins  X-wing

people %>% semi_join(x_wing_pilots, by = c(name = "pilot"))
#> # A tibble: 4 x 11
#>   name  height  mass hair_color skin_color eye_color birth_year gender homeworld

Remote Tables

starwarsdb also includes the entire data set as a DuckDB database, appropriate for teaching and practicing remote database access with dbplyr.

con <- starwars_connect()

people_rmt <- tbl(con, "people")
pilots_rmt <- tbl(con, "pilots")
pilots_rmt
#> # Source:   table<pilots> [?? x 2]
#> # Database: duckdb_connection
#>    pilot             vehicle          
#>    <chr>             <chr>            
#>  1 Chewbacca         Millennium Falcon
#>  2 Han Solo          Millennium Falcon
#>  3 Lando Calrissian  Millennium Falcon
#>  4 Nien Nunb         Millennium Falcon
#>  5 Luke Skywalker    X-wing           
#>  6 Biggs Darklighter X-wing           
#>  7 Wedge Antilles    X-wing           
#>  8 Jek Tono Porkins  X-wing           
#>  9 Darth Vader       TIE Advanced x1  
#> 10 Boba Fett         Slave 1          
#> # … with more rows

x_wing_pilots <- pilots_rmt %>% filter(vehicle == "X-wing")
x_wing_pilots
#> # Source:   lazy query [?? x 2]
#> # Database: duckdb_connection

#> 3 Wedge Antilles    X-wing 
#> 4 Jek Tono Porkins  X-wing

people_rmt %>% semi_join(x_wing_pilots, by = c(name = "pilot"))
#> # Source:   lazy query [?? x 11]
#> # Database: duckdb_connection
#>   name  height  mass hair_color skin_color eye_color birth_year gender homeworld

#> # … with 2 more variables: species <chr>, sex <chr>

DM Tables

Finally, starwarsdb provides a function that returns a pre-configured dm object. The dm package wraps local data frames into a complete relational data model.

library(dm, warn.conflicts = FALSE)

sw_dm <- starwars_dm()
sw_dm
#> ── Metadata ────────────────────────────────────────────────────────────────────
#> Tables: `films`, `people`, `planets`, `species`, `vehicles`, … (9 total)
#> Columns: 58
#> Primary keys: 5
#> Foreign keys: 10

sw_dm %>%
  dm_select_tbl(pilots, people) %>%
  dm_filter("pilots", vehicle == "X-wing") %>%
  dm_apply_filters() %>%
  dm_zoom_to("people") %>%
  semi_join(pilots)
#> # Zoomed table: people
#> # A tibble:     4 x 11
#>   name  height  mass hair_color skin_color eye_color birth_year gender homeworld
#>   <chr>  <dbl> <dbl> <chr>      <chr>      <chr>          <dbl> <chr>  <chr>    
#> 1 Luke…    172    77 blond      fair       blue              19 mascu… Tatooine 
#> 2 Bigg…    183    84 black      light      brown             24 mascu… Tatooine 
#> 3 Wedg…    170    77 brown      fair       hazel             21 mascu… Corellia 
#> 4 Jek …    180   110 brown      fair       blue              NA mascu… Bestine …
#> # … with 2 more variables: species <chr>, sex <chr>
dm_draw(sw_dm)
