我的操作系统是Mac OS Lion
当我在eclipse中启动R（成功安装statet之后，并在R和bash中打包“ rjava，rj和rj-gd”软件包）时，我仍然在图片中收到错误消息。
在ecipse.ini中，我指定了一个vm即
-vm
/usr/bin/java
错误日志包含以下几行。任何帮助将不胜感激
Launching the R Console was cancelled, because it seems starting the R engine failed.
Please make sure that R package 'rj' (0.5.5 or compatible) is installed and that the R library paths are set correctly for the R environment configuration 'R'.

最佳答案
有一个非常简单的解决方案。我在更新StatET插件后遇到了它。
StatET IDE进行了很大的更改，它需要RJ库的新版本（请参见Installation of the R Packages of RJ部分）。
为了安装RJ 1.0（StatET 2.0.x），请键入以下命令：
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.0")
R控制台将再次工作。
希望能有所帮助。
