问题描述
我有几个使用R软件包的Unix服务器，该软件包安装在共享的R库文件夹中.软件包是从此共享文件夹中延迟加载的(默认设置).
I have several unix servers using a R package which is installed on a shared R library folder. The packages are lazy loaded (that's the default) from this shared folder.
现在我要更新软件包:
1)是否可以(而且很干净)在不关闭所有R实例的情况下做到这一点?
1) is it possible (and clean) to do that without closing all R instances?
2)更确切地说，我担心以下问题:
2)a)当我尝试安装已加载的软件包时，从用户界面收到警告:
2)b)来自 https://cran.r -project.org/doc/manuals/r-release/R-ints.html#Lazy-loading ，
2) More precisely, I am concerned about the following:
2)a) The warning I get from the user interface when I try to install a package that is already loaded:
2)b)From https://cran.r-project.org/doc/manuals/r-release/R-ints.html#Lazy-loading,
这是否意味着在对每个对象进行实际评估时，R实例将再次从库文件夹中读取(在这种情况下，这意味着我需要停用延迟加载，或者在更新程序包之前关闭所有R实例)
Does that mean that the R instance will read again from the library folder when doing the actual evaluation of each object (in which case that means I need to either deactivate the lazy loading, or close all R instances before updating the package)
3)还有另一种方法可以在始终运行脚本的服务器网络上维护R软件包，而不必使每个服务器都一个一个地脱机)
3) is there an alternative way to maintain R packages on a network of servers, that are running scripts all the time, without having to put each server offline one by one)

推荐答案
您问过
我可以肯定的是，这是到处都是的工作方式和完成方式.
and I can assure that yes, that it is how works and done everywhere.
至
您读错了.仅建议您重新启动R，以确保新程序包已加载，因为您无法将其插入正在运行的会话中.
you are reading it wrong. An R restart is simply recommended to ensure the new package is loaded as you cannot insert it into a running session.
进一步
您从不需要只需使服务器脱机即可更新用户空间包.例如.例如，当我们每年两次升级整个Ubuntu版本时，我们甚至都不会脱机使用它们.
you never have to take a server off-line just to update a user-space package. E.g. we don't even take them off-line when we, say, upgrade the entire Ubuntu release twice a year.
