下载Rcpp软件包时出现此错误:
> install.packages("Rcpp", dependencies=TRUE)
Installing package(s) into ‘/home/me/src/Rlibs’ (as ‘lib’ is unspecified)

由于我的计算机位于计算机群集上,因此我已经在不同的节点上进行了尝试,并且小心删除了在/ tmp中下载的临时文件。奇怪的是我有权在/ home / me / src / Rlibs /中编写。所以我的问题是:
- 为什么R只想在/ home / me /中拥有写权限,而又想在/ home中具有写权限?
- 我该如何解决错误?
