Rsolnp在Java中使用Renjin
Rsolnp在Java中使用Renjin
提问于 2016-12-19 17:08:41
我试图使用Java程序运行solnp。为了测试这是否有效，我尝试只运行benchmarkids()函数。但我解决不了参考书的问题。我已经在http://packages.renjin.org/package/org.renjin.cran/Rsolnp/上检查了Rsolnp包，据我所知，它可以用renjin装载。
我添加了Maven必需的包：
<dependency>
<groupId>org.renjin.cran</groupId>
<artifactId>Rsolnp</artifactId>
<version>1.16-b28</version>
</dependency>我尝试将包直接添加到我的项目中(我正在使用Eclipse )，但仍然没有工作。
我所犯的错误：

// some other tests to see if 10 * 2 in R works.
public void testRsolnp()
{
RenjinScriptEngineFactory factory = new RenjinScriptEngineFactory();
ScriptEngine engine = factory.getScriptEngine();
try
{
engine.eval("library(rsolnp); benchmarkids();");
}
catch (ScriptException e)
{
e.printStackTrace();
}
// testing code.

R中的包名区分大小写。尝试：engine.eval("library(Rsolnp); benchmarkids();");
