我在基本安装软件包和库调用方面遇到麻烦 [英] I am having trouble with basic installing packages and library calling

问题描述

执行时

install.packages("dplyr")

install.packages("dplyr")

我知道

错误:版本说明"NA"无效另外:警告消息:在utils ::: packageDescription(packageName，fields ="Version")中:找不到软件包"knitr"

Error: invalid version specification ‘NA’ In addition: Warning message: In utils:::packageDescription(packageName, fields = "Version") : no package 'knitr' was found

然后我调用该库，它显然也不起作用-

Then I call the library and it obviously doesn't work either -

库(dplyr)

错误:"dplyr"的程序包或名称空间加载失败:.onLoad在loadNamespace()中对于支柱"失败，详细信息:呼叫:utils :: packageVersion("vctrs")错误:找不到包"vctrs"另外:警告消息:软件包"dplyr"是在R版本3.5.3下构建的

Error: package or namespace load failed for ‘dplyr’: .onLoad failed in loadNamespace() for 'pillar', details: call: utils::packageVersion("vctrs") error: package ‘vctrs’ not found In addition: Warning message: package ‘dplyr’ was built under R version 3.5.3

我正在尝试使用％>％进行突变.根据公司政策，将不会发布完整的代码.我只需要帮助，为什么对我来说，诸如安装软件包和调用库之类的简单操作不起作用...

I am trying to use %>% and mutate. Will not post that full code due to company policy. I just need help with why something as simple as installing packages and calling libraries doesn't work for me...

推荐答案

您尝试过

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

?

让我知道这是否行不通.

Let me know if this doesn't work.
