Question

当尝试在Ubuntu 14.04 LTS 32位上安装插入程序包时，我收到以下警告

The downloaded source packages are in

Answer 1

在安装“脱字符”包之前，您需要安装所有依赖项。

install.packages(c('lme4', 'pbkrtest', 'BradleyTerry2', 'car', 'caret'))

上面的代码应该可以解决这个问题。

或者你可以使用：

install.packages('caret', dependencies = TRUE)

然后，您可以尝试使用上面的命令安装'nloptr‘包。
