jDeployR ~ DeployR Java Client Library.

This library provides a simple API for integrating DeployR authenticated, asynchronous and anonymous services into Java applications.

The basic usage pattern for authenticated services, working with R projects is as follows:

1. Create a client connection to DeployR:

RClient rClient = RClientFactory.createClient(deployrUrl);

2. Login on the connection:

RUser rUser = rClient.login(new RBasicAuthentication("testuser", "TESTUSER_PASSWORD"));

3. Create a project:

RProject rProject = rUser.createProject("Test Project", "Brief description.");

4. Execute R code on the project:

RProjectExecution rExecution = rProject.executeCode("x <- c(1:10); plot(x,x);");

5. Optionally, save the project:

RProjectDetails rProjectDetails = rProject.save();

6. Close the project:

rProject.close();

7. Logout and release all resources on the connection:

rClient.release();

The basic usage pattern for asynchronous services, working with jobs is as follows:

1. Create a client connection to DeployR:

RClient rClient = RClientFactory.createClient(deployrUrl);

2. Login on the connection:

RUser rUser = rClient.login(new RBasicAuthentication("testuser", "TESTUSER_PASSWORD"));

3. Submit job for background execution:

RJob rJob = rUser.submitJobCode("Test Job", "Brief description of job.", "x <- c(1:10); plot(x,x);")

4. Query the status of job:

RJobDetails rJobDetails = rJob.query()

5. When job status is completed, retrieve result as a project:

if(rJobDetails.status.equals(RJob.COMPLETED)) {

RProject jProject = rUser.getProject(rJobDetails.project)

}

6. Logout and release all resources on the connection:

rClient.release();

The basic usage pattern for anonymous services, executing published R scripts is as follows:

1. Create a client connection to DeployR:

RClient rClient = RClientFactory.createClient(deployrUrl);

2. Execute a published R Script anonymously:

RScriptExecution rExecution = rClient.executeScript(scriptName, scriptDirectory, scriptAuthor, scriptVersion, scriptExecuteOptions);

3. Retrieve any R Script workspace objects on the response:

List<RData> workspaceObjects = rExecution.about().workspaceObjects;

4. Retrieve any R Script plot results on the response:

List<RProjectResult> results = rExecution.about().results;

5. Retrieve any R Script file artifacts on the response:

List<RProjectFile> artifacts = rExecution.about().artifacts;

6. Logout and release all resources on the connection:

rClient.release();

Once a client connection has been established it can be used to submit any number of API calls up until the point where the connection is released or timed-out. Each client connection behaves as if all calls on the connection are made within the context of a single HTTP session on the server.
