问题描述
我通过以下方式为StatEt安装了RJ:
I installed RJ for StatEt with:

Installiere Pakete nach 'C:/Users/eis/Documents/R/win-library/3.4'

在StatEt Eclipse首选项中进入R_LIBS:

推荐答案
RJ 2.1与Java 9.0.1不兼容.如果已安装，则可以指向不同版本的JAVA.请安装Java 8并在运行配置中选择JRE 8，例如:
RJ 2.1 is not compatible to Java 9.0.1. You can point to different versions of JAVA if you have them installed. Please install Java 8 and select JRE 8 in your run configuration, for example:
我对R环境配置的更改不多
I don't change much my R environment configuration
