starwarsdb
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.

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

people_rmt <- tbl(con, "people")

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

dm_select_tbl(pilots, people) %>%
