rsgl

rsgl implements the SGL graphics language for use within R. SGL is a graphics language that is designed to look and feel like SQL, and is based on the grammar of graphics.

Installation

To install the official CRAN release:

install.packages("rsgl")

If you instead want the development version, install from GitHub with:

# install.packages("devtools")
devtools::install_github("sgl-projects/rsgl")

Usage

dbGetPlot is the primary interface to rsgl. It takes a DBI database connection and a SGL statement and returns the corresponding plot.

The following example demonstrates creating a DBI connection to an in-memory DuckDB database, loading it with data, and then generating a scatterplot from a SGL statement.

library(duckdb)
#> Loading required package: DBI
library(rsgl)
#> 
#> Attaching package: 'rsgl'
#> The following objects are masked from 'package:datasets':
#> 
#>     cars, trees

con <- dbConnect(duckdb())
dbWriteTable(con, "cars", cars)

dbGetPlot(con, "
    visualize
        horsepower as x,
        miles_per_gallon as y
    from cars
    using points
")
