[R] How to save and restore a workspace

[PIKAL Petr]

Hi Don

This is matter of opinion

There is some basic menu items in RGui which is not in terminal. This could be quite confusing if you are used to have each project in separate directory and want to switch to it (I know about setwd command however in that case point and click is much more convenient).

But as I said, it is matter of opinion.

For Jon

I usually do not start R from its icon. I make a new folder for each project for which I want to use R and keep .RData and .Rhistory in it.

Try to set a new folder named e.g. "stat" somewhere.
Locate .RData and .Rhistory files and copy it to this folder.
Double click on .RData to start R (or select R as a program to open this file)
You can open .Rhistory in any suitable text editor (Notepad, Tinn, ...) to reuse commands in it.

Alternative:

After starting R, you can change working directory (setwd or through menu item). After this change, any saved object together with .RData or Rhistory will go into this directory. You could also set a shortcut icon to this directory on your desktop by copiing original icon, renaming it and manually changing desired directory.

Cheers
Petr
