adbcsqlite

The goal of adbcdrivermanager is to provide a low-level developer-facing interface to the Arrow Database Connectivity (ADBC) SQLite driver.

Installation

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()

Example

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") |>
  tibble::as_tibble()
