存储(几乎)列表中工作区中的所有对象 [英] Store (almost) all objects in workspace in a list

问题描述

比方说，我的工作空间(全局环境)中有许多对象，并且我想将大多数对象存储在列表中.这是一个简化的示例:

Let's say that I have many objects in my workspace (global environment) and I want to store most of those in a list. Here's a simplified example:

# Put some objects in the workspace
A <- 1
B <- 2
C <- 3

我想将对象A和C存储在一个列表中.当然，我可以明确地做到这一点:

I would like to store objects A and C in a list. Of course, I can do that explicitly:

mylist <- list(A,C)

但是，当工作空间中的对象数量很大时，这将变得很麻烦.因此，我想采取不同的方法并尝试以下操作:

However, when the number of objects in the workspace is very large, this would become rather cumbersome. Hence, I would like to do this differently and attempted the following:

mylist <- list(setdiff(ls(),B))

但这显然不是我想要的，因为它仅将对象的名称存储在工作空间中.

But this obviously is not what I want, as it only stores the names of the objects in the workspace.

关于如何执行此操作的任何建议?

Any suggestions on how I can do this?

非常感谢！

推荐答案

另一种选择是使用mget:

mget(setdiff(ls(),"B"))
