如何安装插入符号包。 尝试 install.packages("caret") 但出现错误

Question

install.packages("caret")以下错误后：

Installing package into ‘...../R/win-library/3.4’
(as ‘lib’ is unspecified)
also installing the dependencies ‘rlang’, ‘recipes’


  There are binary versions available but the source versions are later:
        binary source needs_compilation
rlang    0.3.4  0.4.0              TRUE
recipes  0.1.5  0.1.6             FALSE
caret   6.0-81 6.0-84              TRUE

Warning in install.packages :

我也试过并安装了“rlang”包。 它依赖于“recepies”包，所以再次下载了它......

安装后收到此消息。

 :Warning in install.packages :
  package ‘recepies’ is not available (for R version 3.4.4)

我需要加载要安装的插入符号包。

如果您使用的是 Windows，请尝试以下操作：

将您的库添加到 libpaths； 看到这个答案。 之后尝试安装软件包； 看到这个答案：

install.packages("caret", dependencies=TRUE, type="win.binary")
