Question

我正在R中运行一个经常重启的服务器进程，它使用许多R包。现在，每次重启都会创建一个临时目录，其中包含一些带有“rds”扩展名的文件。我真的想知道哪个R包或功能导致创建这些.rds文件（所以我可以禁用它）。谢谢！

文件名如下所示：

libloc_％2fusr％2flib％2FR％2flibraryVersion，优先级，取决于进口，LinkingTo，顾名思义，提高，操作系统类型，许可，Archs，Built.rds

并且内容的开头如下所示：

它看起来像installed.packages()创建的文件。检查此功能的来源。

也许您已在启动资料中调用它（例如会话开始时为update.packages()）？

您可以启用saveRDS功能的跟踪，例如添加到.Rprofile：

trace("saveRDS", function() print(str(head(sys.calls(),-5))))

这将打印（您也可以将其转储到文件中）调用堆栈，例如当我运行update.packages(ask='graphics')然后在控制台上我得到了：

Tracing saveRDS(res0, dest, compress = TRUE) on entry 
List of 3
 $ : language update.packages(ask = "graphics")
 $ : language available.packages(contriburl = contriburl, method = method)
 $ : language saveRDS(res0, dest, compress = TRUE)
NULL
Tracing saveRDS(res0, dest, compress = TRUE) on entry 
List of 3
 $ : language update.packages(ask = "graphics")
 $ : language available.packages(contriburl = contriburl, method = method)
 $ : language saveRDS(res0, dest, compress = TRUE)
# ..... and few more calls ...............

在R中创建“libloc_％2f ... Builts.rds”临时文件的原因是什么？
