The goal of adbcdrivermanager is to provide a low-level developer-facing interface to the Arrow Database Connectivity (ADBC) SQLite driver.
You can install the released version of adbcsqlite from CRAN with:
install.packages("adbcsqlite")You can install the development version of adbcsqlite from GitHub with:
# install.packages("pak")
pak::pak("apache/arrow-adbc/r/adbcsqlite")ADBC drivers for R use a relatively new feature of pkgbuild to enable installation from GitHub via pak. Depending on when you installed pak, you may need to update its internal version of pkgbuild.
install.packages("pkgbuild", pak:::private_lib_dir())
pak::cache_clean()This is a basic example which shows you how to solve a common problem:
library(adbcdrivermanager)
# Open a new connection to a database
db <- adbc_database_init(
adbcsqlite::adbcsqlite(),
uri = ":memory:"
)
con <- adbc_connection_init(db)
# Write a table
nycflights13::flights |> write_adbc(con, "flights")
# Issue a query
con |>
read_adbc("SELECT * from flights") |>
