无法在R版本3.2.3中完全安装软件包("caret")

Question

> 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"pbkrtest"然后我试图重新安装它.

我在 Windows 7 上也遇到了这个问题。我按照顺序执行了以下步骤，结果成功了。a) 确保您的 R 版本已更新为最新的 R 版本 3.2.3 b) 默认源似乎正在安装 Unix 版本。所以我手动下载了适用于 Windows 的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软件包。
