我正在嘗試使用Java運行R。我在我的Mac上安裝了R,並且從終端使用過很多次。通過Java從終端運行R
在終端,啓動R,一個簡單的類型 「R」
例:
Macintosh-11:Desktop myname$ R

所以,我想要做的是通過Java運行R,通過終端的內容。所以,我寫了自己的Java類:
public class javar {
public static void main(String[] args) throws Exception {
Runtime.getRuntime().exec("R");
}
}
然而,當我編譯,然後執行,使用
java javar
我沒有看到[R開始。我只是看到程序完成執行,然後終端準備好另一個命令。
我該如何實現我想要做的?
你們是不是要運行腳本或有一個互動的控制檯? – Clint 2011-04-29 15:21:55
