我最近做毕业设计，其中需要用到一个文章的作者附的自己写的package，R的cran上面并没有，只能从作者自己主页上把包下载下来然后安装。我遇到了如下的问题，我谷歌了很多解决方案，包括安装rtools什么的，但依然安装不上，在这个问题上已经花了一周多了，实在没办法了，希望能够得到大家的帮助。无论大家的方法是否能帮到我我都感谢大家！
我的命令以及反馈的错误是这样的：
install.packages("D:/SVMW_0.2.tar.gz", repos = NULL, type = "source")
Installing package into ‘C:/Users/wtz/Documents/R/win-library/3.3’
