[BlindRUG] Emacs for Statistical Applications with Screen Readers

Hello,

Thank you Robin and others,
I have started using "R" in Emacs, and it is running really well. The
problem appears after saving, when I reopen the file, (example.r), it
does not display the changes made by me in the last session.
Can anybody tell, Why it would be happening?
And, Mr. Jonathan your compilation of "R" commands is extremely useful.

Thank you
Laxmisagar
