这是一个函数阴影错误吗?

标签: r package data.table shadowing

在搜索中没有任何适用的内容,但在R:

中安装软件包时遇到了此错误
> install.packages("entropy")
Loading required package: stats

Attaching package: ‘zoo’

The following objects are masked from ‘package:base’:

    as.Date, as.Date.numeric

Error in eval(expr, envir, enclos) : could not find function "data.table"
Calls: source -> withVisible -> eval -> eval
Execution halted
Warning in install.packages :
  installation of package ‘entropy’ had non-zero exit status

现在,我在此运行会话中加载了data.table。当我以root身份运行另一个R会话并安装此包而没有加载新包时,它完成没有错误,我可以将此包加载到初始会话中没有问题。

这个错误来自哪里,如果我同时加载了data.table,它是否会给我带来错误输出?

编辑:conflicts()的输出:

已安装的软件包列表位于this pastebin,因为它很长。
