> require("caret")
  Loading required package: caret
  Loading required package: lattice
  Loading required package: ggplot2
  Error in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck =      vI[[j]]) : 
   there is no package called ‘pbkrtest’

所以我发现缺少＆＃34; pbkrtest＆＃34;然后我试着重新安装它。

Answer 1

我在Windows 7上也遇到了这个问题。我按顺序执行了以下步骤并且它有效。 a）确保您的R版本更新最新的R版本3.2.3 b）默认源似乎是安装Unix版本。所以我为Windows手动下载了https://cran.r-project.org/web/packages/pbkrtest/index.html c）使用R菜单中的手动安装功能来安装包。

干杯，拉坦

在控制台中输入version检查R的版本。如果版本不“ version.string R版本3.3.2 ”或更高版本
从https://cran.r-project.org/bin/windows/base/
使用Tools =＆gt;更新R版本RStudio中的全局选项。
在您的控制台中使用“install.packages("caret")”安装软件包。
执行require(caret)。
使用?createDataPartition进行测试。

无法在R版本3.2.3中完全安装软件包（＆＃34;插入符号＆＃34;）
