我正在用R编写一个包。我运行devtools :: check（）没有问题。然后我运行包goodpractice（），它告诉我以下错误
Preparing: covr
Preparing: cyclocomp
Error:
Build failed, standard output:
* checking for file ‘EndoMineR/DESCRIPTION’ ... OK
ERROR
copying to build directory failed
Standard error:
cp: error writing '/tmp/Rtmpy74ibO/Rbuild1ae3169e0658/EndoMineR/.git/objects/74/8f2d9ae99fac31a977033245508f76a97742ba': No space left on device
我检查了项目中的文件大小，并且有很多git对象和RData文件看起来很大。我该如何预防/清除它们？
我已经尝试了rm(list = ls())但是没有任何事情被清除。重新启动R会话也无法帮助重启计算机....
按尺寸排列的前18个文件是：
