[BlindRUG] Emacs for Statistical Applications with Screen Readers

Hi Laxmisagar,

No problem. To begin, it's probably worth checking your installation is working as it should. Can you try launching R from within Emacs with the command Alt+x and then the letter R? The process should launch, and ask you to choose the path in which to start R's working directory. you can just use the default for now, so press enter. You should then have the R terminal window opened from within Emacs, and have the cursor positioned after the > prompt. Then just try executing some simple commands (2+3, 4*8, etc). You will be able to press the up arrow to read R's output, and shouldn't need to use the JAWS cursor.

Let me know how you get on.

cheers,
Robin

Hi Robin,

Thanks for the time, I have added R to the path environment variable, but unable to edit anything on the emacs buffer.
can I directly start writing R commands in the emacs buffer? or something else is required?
I am a beginner in this, hence would request for a detailed instructions.

Thank you
Laxmisagar
