R: The workspace

The workspace is held in the computer's memory. It keeps, for examples, variable definitions.

ls shows the variables and functions that are defined in the current workspace.

Use rm to delete (remove) variables from the workspace.

The workspace can be saved to disk with save.image("filename").

If R is started with the --no-restore startup option, a previously saved workspace is not restored. Similarly, with --no-save, R does not write a workspace file when R is exited.
