我正在尝试在 Windows 7上为R-2.14.0安装软件包rpart,但是我收到了警告：

package ‘rpart’ is not available (for R version 2.14.0)

所以我从包页面下载tar.gz文件.我已经安装了Rtools但是我禁用了所有选项,包括更改PATH的选项.然后我做以下事情：

> install.packages("C:/rpart_3.1-50.tar.gz",type="source")
Installing package(s) into ‘C:/Users/backupSam/Documents/R/win-library/2.14’
(as ‘lib’ is unspecified)

Warning messages:

2: In install.packages("C:/rpart_3.1-50.tar.gz",type = "source") :
  installation of package ‘C:/rpart_3.1-50.tar.gz’ had non-zero exit status

有什么建议？

解决方法

因为你必须设置PATH,但是你因为害怕你可能会软化某些东西而犹豫不决,你可以通过以下方式在R会话中暂时执行：

pathRtools <- paste(c("c:Rtoolsbin","c:RtoolsMinGWbin","c:MiKTeXmiktexbin","c:Rbini386","c:windows","c:windowssystem32"),collapse=";")
Sys.setenv(PATH=paste(pathRtools,Sys.getenv("PATH"),sep=";"))
