您好，我正在尝试在 Eclipse 中安装 R。起初我收到以下错误消息
"Launching the R Console was cancelled, because it seems starting the
R engine failed. Please make sure that R package 'rj' (2.0 or compatible)
is installed and that the R library paths are set correctly for the R
environment configuration 'R firstRTest'."
我发现有人有同样的错误：StatET in Eclipse and R
但是，当我继续执行建议的解决方案时，我运行了：
install.packages(c("rj", "rj.gd"), repos="http://download.walware.de/rj-1.0")
在 R 控制台中，我收到以下错误消息：
packages ‘rj’, ‘rj.gd’ are not available (for R version 3.1.2)
任何帮助表示赞赏。我是新手，所以请为我保持简单（尽可能简单）。
