无法安装ggplot2
我在将 ggplot2 安装到 R 中时遇到问题。我环顾四周，没有看到与我遇到的相同错误。
> install.packages('ggplot2', dep=TRUE)
Warning in install.packages("ggplot2", dep = TRUE) :
'lib = "C:/Program Files/R/R-2.13.1/library"' is not writable
Error in install.packages("ggplot2", dep = TRUE) :
unable to install packages
Can anybody help?

The other advice you're getting is good and should be preferred, but you can run R (or RStudio) as an administrator (right-click on the .exe and "Run as Administrator" is an option) which should give it write access to your library.
在RStudio中：
