我曾经用它来尝试安装车载套件：
install.packages("car", dependencies=TRUE, INSTALL_opts = c('--no-lock'))
但收到此错误：
ERROR: dependency ‘openxlsx’ is not available for package ‘rio’
* removing ‘/home/dan-laptop/R/x86_64-pc-linux-gnu-library/3.2/rio’
Warning in install.packages :
installation of package ‘rio’ had non-zero exit status
ERROR: dependency ‘rio’ is not available for package ‘car’
* removing ‘/home/dan-laptop/R/x86_64-pc-linux-gnu-library/3.2/car’
Warning in install.packages :

ERROR: dependency ‘car’ is not available for package ‘alr4’
* removing ‘/home/dan-laptop/R/x86_64-pc-linux-gnu-library/3.2/alr4’
Warning in install.packages :

我尝试单独安装依赖项，但是没有运气。任何帮助将不胜感激。谢谢。
