LINQ with R

Together at last

---

Quick Start

Install the package:

# install.packages("remotes")
library("remotes")
remotes::install_github("phillc73/queryjlr")
library("queryjlr")

Run the setup function:

queryjlr_setup()

If your Julia installation is not found, it is possible to define the path to it. For example:

queryjlr_setup(julia_home = "/home/phillc/bin/julia-1.5.3/bin")

If this path is incorrect, all else fails.

Both the Query and DataFrames packages from Julia will be loaded, and installed if not present, during queryjlr_setup

Then try the following:

linqr("@from i in mtcars begin
    @where i.disp > 200
    @select {i.mpg, i.cyl}
    @collect DataFrame
end")

For more about writing these types of queries, refer to the Query.jl documentation.

Finally, have fun!

This package is only possible thanks to:

• Non-Contradiction's JuliaCall R package
• davidanthoff's Query.jl Julia package
