r - 安装ggp​​lot “subscript out of bounds” 错误

Question

$ R
R version 2.12.2 (2011-02-25)
Platform: i486-pc-linux-gnu (32-bit)

> install.packages("ggplot2", dep="T")
Error in apply(available[p1, dependencies, drop = FALSE], 1L, function(x)  paste(x[!is.na(x)],  : 
  subscript out of bounds

我可以做什么来安装 ggplot2？

Answer 1

请阅读函数的帮助!来自 ?install.packages我们有:

dependencies: logical indicating to also install uninstalled packages
          on which these packages depend/suggest/import (and so on
          recursively).  Not used if ‘repos = NULL’.  Can also be a
          character vector, a subset of ‘c("Depends", "Imports",
          "LinkingTo", "Suggests", "Enhances")’.

所以这清楚地表明你需要提供一个逻辑值，一个 TRUE或 FALSE . "T"不合逻辑 TRUE也不是 T真的。总是拼出TRUE和 FALSE否则你会遇到很多麻烦。节省几次按键的麻烦是不值得的。

正如我在上一个问题的回答中所展示的:

R> install.packages("ggplot2", dependencies = TRUE)

作品。那么你为什么要改变我展示给你的工作呢？
