是什么创建了“libloc_%2f...Builts.rds” R 中的临时文件？

Question

我正在 R 中运行一个经常重新启动的服务器进程，并且使用许多 R 包。现在，每次重新启动都会创建一个临时目录，其中包含几个扩展名为“rds”的文件。我真的很想知道哪个 R 包或功能会导致创建这些 .rds 文件（这样我就可以禁用它）。谢谢！

文件名如下所示：

libloc_%2fusr%2flib%2fR%2flibraryVersion,Priority,Depends,Imports,LinkingTo,Suggests,Enhances,OS_type,License,Archs,Built.rds

内容的开头如下所示：

Answer 1

它看起来像由 installed.packages() 创建的文件。检查该函数的来源。

也许您在启动配置文件中调用了它（例如会话启动时的 update.packages() ）？

您可以启用对 saveRDS 函数的跟踪，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=' 时Graphics') 然后在控制台上我得到：

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 ...............
