推荐答案

它似乎崩溃了，因为它试图更新摘要所依赖的软件包，由于使用中而无法删除。

It seems to be crashing because it tries to update the digest package upon which it depends, and fails to remove it because it's in use.

关闭R，然后导航至 C：/ Users /Nicholas/Documents/R/win-library/3.2 并删除 digest 文件夹。然后，启动R并再次尝试安装。

Close R and then navigate to C:/Users/Nicholas/Documents/R/win-library/3.2 and delete the digest folder. Then, launch R and try the install again.
