ClojisR template

Template to get started with ClojisR - a wrapper library exposing APIs for calling R functions on R objects in Clojure

It contains a Dockerfile which has Clojure and all the dependencies for ClojisR.

Usage

Clojure projects including ClojisR can now be created quickly in 2 ways from the latest stable template:

• without clj-new installed in user deps.edn

# example
clj -Sdeps '{:deps {seancorfield/clj-new {:mvn/version "1.0.199"}}}' \
  -m clj-new.create clojisr-template <org-name>.<app-name>

• with clj-new installed in user deps.edn (recommended)

# example
clj  -X:new :template clojisr-template :name <org-name>.<app-name>

NOTE: this assumes you have clj-new configured in your ~/.clojure/deps.edn profile.

Creating docker image

The template creates a Dockerfile in the project folder. The docker image can be build with

cd <org-name>.<app-name>
docker build . -t <app-name>

The Dockerfile assumes that the local project directory gets mounted into a folder in the container and that it becomes the working directory. The docker image runs a nRepl on port 12345 which can be connected to by any other nRepl compatible client (including emacs+Cider)

A typical command line for running the nRepl server in a docker container is then this:

docker run -ti -p 12345:12345 <app-name>

Using ClojisR in repl

Now Emacs (or any other nRepl client) can be connected to localhost:12345.

Example to use clj as nRepl client:

lein repl :connect 12345

In this connected repl ClojisR works out of the box:

(require '[clojisr.v1.r :refer [r]])
(r "1+1")
