在Eclipse和R中的StatET [英] StatET in Eclipse and R

问题描述

我已经设法将StatET安装到eclipse中，我有一个名为Test的Java项目，其中包含一些代码。我希望能够将.R文件保存在该项目文件夹中，并将其作为独立的R脚本运行，与Java程序分开。我该怎么做？如果我尝试突出显示.R文件中的一些R代码并运行它，它说在当前工作台窗口中没有R的活动。

更新：
我添加了一个运行配置，我现在在弹出框中出现以下错误，当我尝试运行R脚本：

 启动R控制台已被取消，因为似乎启动了R引擎失败。 
请确保安装了R包'rj'（1.0.0或兼容），R库路径设置为R环境配置'R'
  

解决方案

您需要先从Eclipse中启动R控制台。选择运行 - >从菜单栏运行配置... 。如果您尚未创建R配置，则可以通过右键单击 R控制台来创建新配置。欲了解更多信息，Longhow Lam组织了一个不错的指南（PDF）。

关于您的新错误消息，请确保 rj



安装。包（c（rj，rj.gd），repos =http://download.walware.de/rj-1.0）

对于开发StatET 3.0：

install.packages（c（rj，rj.gd），repos =http://download.walware.de/rj-1.1）

对于旧的StatET 0.10：

install.packages（rj，repos =http://download.walware.de/rj-0.5）

I've managed to install StatET into eclipse, and I have a Java project called "Test" with some code in there. I'd like to be able to keep a .R file in that project folder and run it as a stand alone R script, seperate from the Java program. How can I do this? If I try to highlight some R code in a .R file and run it, it says "No session of R is active in the current workbench window."

Update: I added a run configuration and I now have the following error in a pop up box when I try to run the R script:

Launching the R Console was cancelled, because it seems starting the R engine failed. 
Please make sure that R package 'rj' (1.0.0 or compatible) is installed and that the R library paths are set correctly for the R environment configuration 'R'

解决方案

You need to first start an R console from within Eclipse. Select Run -> Run Configurations... from the menu bar. If you have not already created an R configuration, you can create a new one by right-clicking on R Console. For more information, Longhow Lam put together a nice guide (PDF).

EDIT: Regarding your new error message, make sure rj is installed in R by running one of these commands in the command-line version of R. For the current StatET 2.0:

install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.0")

For the development StatET 3.0:

install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.1")

For the old StatET 0.10:

install.packages("rj", repos="http://download.walware.de/rj-0.5")
