我看到了这个问题的一个版本，但仍然没有看到答案。我试图使用ggplot2，但得到以下错误
Error in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]) :
there is no package called ‘stringi’
Error: package or namespace load failed for ‘ggplot2’
我安装了stringi - 导致此错误
There is a binary version available but the source version is
later:
binary source needs_compilation
stringi 0.5-2 0.5-5 TRUE
Binaries will be installed
trying URL 'http://cran.rstudio.com/bin/windows/contrib/3.2/stringi_0.5-2.zip'
Warning in install.packages :

Error in download.file(url, destfile, method, mode = "wb", ...) :

Warning in install.packages :
download of package ‘stringi’ failed
然后我读了这个问题 - package 'stringi' does not work after updating to R3.2.1。并遵循使用该选项并为我的Windows版本获取二进制文件的建议
> options(install.packages.check.source = "no")
> install.packages("stringi",type="win.binary")

现在我的分析因此而停滞不前;没有ggplot2。
