我正在尝试安装slitify，但它返回了一个错误。我想是目录名造成的。

我是R的新手，我甚至尝试了以下代码手动安装它：
> pkgs = c("slidify","slidifyLibraries")
> install.packages(pkgs,lib="C:/Users/matte_000/Documents/R/win-library/3.0","https://github.com/ramnathv/slidify/archive/master.zip", repos = NULL)
Warning in install.packages :
packages ‘slidify’, ‘slidifyLibraries’ are not available (for R version 3.0.1)
Warning in install.packages :

最后，如果它有助于我发布sessionInfo（）的结果，在Windows 8 x64上运行：

你有什么办法修理它吗？我在谷歌上搜索了一下，但没有发现任何有用的
尝试此方法，从Windows命令提示符安装slidifyLibraries
