[R] How to delete the previously saved workspace restored

[Yanwei Tan]

Dear all,

I am a new user of R, here I have a question about remove the previous
restored workspace. I saved the workspace last time, but R always
automatically load the workspace when I open it. I try to remove the
object and then close R without saving. But next time when I open R, it
always load the previous workspace. I want to delete the .RData in the
directory, but I have no clue where is the .RData directory.

The message is "Workspace restored from /Users/wei/.RData"

How could I avoid from this directory? because there is a dot before, I
do not know where I can find this file.

Also I already try this command : rm(list=ls()) But R still load the
previous workspace.

With many thanks for any advice!!

Best,
Wei

It tells you that it is in the /Users/wei/ directory.

What OS? MacOSX? You can turn on showing dotted files which are by
default hidden. Or you could open a Terminal window and issue the
command

rm /Users/wei/.RData

You could alternatively exit and save after rm(list=ls()) which would
create an empty workspace which should load very quickly.

If you start R, type :

unlink(".RData")

This deletes the workspace file.

The easiest way (I use WIndows) is to start each session without
loading the previous workspace. I explicitly save what I need and
then explicitly restore it. In most cases, I always reconstruct the
data I need.

I use the '--no-restore --no-save' options.

What is the problem that you are trying to solve?

Thanks a lot David!

I use MacOSX and deleted the .RData file, then everything is fine.

Best wishes,
Wei
