【问题描述】：
我最近删除了几个 R 包（使用 remove.packages()），并重新安装了它们的最新版本。我尝试使用以下语法重新安装库网格：
url <- "https://cran.r-project.org/src/contrib/Archive/grid/grid_0.7-4.tar.gz"
pkgFile <- "grid_0.7-4.tar.gz"
download.file(url = url, destfile = pkgFile)
install.packages(pkgs=pkgFile, type="source", repos=NULL)
unlink(pkgFile)
我收到以下警告和错误：
Error : Invalid DESCRIPTION file
Invalid package name.
This is the name of a base package.
See section 'The DESCRIPTION file' in the 'Writing R Extensions'
manual.
ERROR: installing package DESCRIPTION failed for package ‘grid’
* removing ‘/Library/Frameworks/R.framework/Versions/3.3/Resources/library/grid’
Warning in install.packages :
installation of package ‘/Users/lindz/RNASeqVisualization/grid_0.7-4.tar.gz’ had non-zero exit status
网格现在似乎是基础 R 的一部分，所以我暂时继续前进。但是，在重新安装包 ggplot2 时，使用：
install.packages("ggplot2")
我收到以下警告：

然后我跑的时候：
library(ggplot2)
我收到了错误：
Error : package ‘grid’ does not have a namespace
Error: package or namespace load failed for ‘ggplot2’
我现在不确定该怎么做。我看过类似的帖子 (R error package grid does not have a namespace)，但他们的解决方案不适用于我。我的任何库中都没有保存网格，因为我已经卸载了它（使用 remove.packages()）。
我的 sessionInfo() 如下：
R version 3.3.1 (2016-06-21)
Platform: x86_64-apple-darwin13.4.0 (64-bit)
Running under: OS X 10.9.5 (Mavericks)

other attached packages:

任何建议将不胜感激！
