keep: Remove All Objects, Except Those Specified

Description

Remove all objects from the user workspace, except those specified.

Usage

keep(..., list=character(0), all=FALSE, sure=FALSE)

Arguments

...

objects to be kept, specified one by one, quoted or unquoted.

list

character vector of object names to be kept.

all

whether hidden objects (beginning with a .) should be removed, unless explicitly kept.

sure

whether to perform the removal, otherwise return names of objects that would have been removed.

Value

• A character vector containing object names, or NULL when sure is TRUE.

Details

Implemented with safety caps: objects whose name starts with a . are not removed unless all=TRUE, and an explicit sure=TRUE is required to remove anything.
