Running Forecast in Renjin

I need to execute some R scripts that process timeseries and perform forecast over them. I am using the forecast package and everything works fine when executing the script from R console.

However, I always get the same exception when trying to do the same thing with Renjin: Could not load package org.renjin.cran:colorspace

It seems that there is some dependency missing so I am wondering, if there is some workaround for that.

This is the java/Renjin code (just loading forecast in this example) I am trying to execute:

private void testRenjin() throws ScriptException {
    ScriptEngineManager manager = new ScriptEngineManager();
    ScriptEngine engine = manager.getEngineByName("Renjin");

    // check if the engine has loaded correctly:
    if (engine == null) {
      log.debug("Error creating Renjin.");
    }

    engine.eval("library(forecast)");
  }

I have set the necessary dependencies in my pom.xml:

    <dependency>
        <groupId>org.renjin</groupId>
        <artifactId>renjin-script-engine</artifactId>
        <version>0.7.0-RC7</version>
    </dependency>

    <dependency>
        <groupId>org.renjin.cran</groupId>
        <artifactId>forecast</artifactId>
        <version>4.04-SNAPSHOT</version>
    </dependency>

I would be glad for any help.

The forecast package includes C++ code which is not yet supported by Renjin. (Issue #119)

You can always find the latest updates on package compatability on packages.renjin.org:
