org.rosuda.REngine.REXPGenericVector@2d59a372+[9]named輸出結(jié)果為向量？

最近在做一個項目，需要用到j(luò)ava調(diào)用Rserve執(zhí)行R語句，代碼如下：

 xp=c.eval("eperson(economic)");
    System.out.println("----eperson(economic).asList()-----");
    Object[] array= xp.asList().toArray();
    for(int i=0;i<=array.length-1;i++){
        System.out.println(array[i]);
    }
    System.out.println(xp.isVector());
    if(xp.isRecursive()){//xp是否為遞歸對象
         for(int i=0;i<xp.length();i++){
             System.out.println((xp.asList().get(i)));//values() 
             System.out.println("---------");
             System.out.println((xp.asList().values()));
             System.out.println("---------");
             System.out.println(xp.asList().toString());
            
         }
    }

代碼輸出結(jié)果如下：

結(jié)果并不是我想要的，我希望返回的結(jié)果是，能夠打印出結(jié)果的具體值，即將R語句在R編輯器里運行時后得到結(jié)果：

該怎么寫代碼呢？
