在我的自定义R版本上安装旧版本的插入符号是一种负担。 我尝试使用RStudio安装工具，但失败了
我尝试了命令：
pathToFile <- "C:/Users/Fsociety/Desktop/caret_5.17-7.tar"
install.packages(pathToFile,repos = NULL, type = "source")
我收到了这个错误：
Warning: invalid package 'C:/Users/Fsociety/Desktop/caret_5.17-7.tar'
Error: ERROR: no packages specified
Warning in install.packages :
running command '"C:/PROGRA~1/RRO/RRO-32~1.0/R-32~1.2/bin/x64/R" CMD INSTALL -l "C:\Users\Fsociety\Documents\R\win-library\3.2" "C:/Users/Fsociety/Desktop/caret_5.17-7.tar"' had status 1
Warning in install.packages :
installation of package ‘C:/Users/Fsociety/Desktop/caret_5.17-7.tar’ had non-zero exit status
我可以修复install.package有什么问题吗？
