安装ggp​​lot"下标越界"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

我该怎么做才能安装ggp​​lot2？

Answer 1

请阅读功能帮助!从?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,a TRUE或a FALSE."T"是不合逻辑的TRUE,也不是T真的.总是拼出来TRUE,FALSE否则你会遇到很多麻烦.节省一些按键是不值得的麻烦.

正如我在前一个Q的回答中所示:

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

作品.那么你为什么要改变我所展示的作品？
