Viewing all the objects in R in a buffer in Emacs

You also probably did not read the complete Emacs-Speaks-Statistics manual… ? By chance, I discovered a nice feature, called Rdired.
This command gives you a dired-buffer with all your objects. In this buffer you can view, edit and plot your R-objects. It is documented in chapter 12.9 of the manual.
Here is small example: In the buffer in the middle, you see the original code taken from the manual. I invoked ess-rdired and the lower buffer is shown. I then put the cursor on the line with the parameter s and hit “v”. This gave me the upper buffer with all the values. Then I hit the “p” and a nice plot is shown. With “d” you could delete the object.
You have to put the following lines in your .emacs file:

Auto-Completion in Emacs, LaTeX and Gams

The fun with Emacs is that you can discover new (or old) stuff that makes your life much easier on an almost weekly base. I was reading the manual on Emacs Speaks Statistics and discovered that there is a mode called auto-completion. I googled it, installed it and after some experimenting, I got it running. You can find it here. It comes with autocompletion for some programming languages (Python, Ruby, C+, etc.) but not for LaTeX, so I googled further and discovered an extension called auto-complete-latex (you can download it here.
Here are some screenshots: You just start typing and it suggests a keyword or if you wait a little bit longer it gives you a dropdown llist. You can jump to the next suggestions using the tab-key.
It doesn’t matter if you use capitals or not:
and it also keeps track of words in the actual document. Here an example of my paper on parking. As you see the word “Parking appears, when I typ “par”.
For Gams there is no dictionary, so I wrote one myself and added it to the dictionaries. I only did not manage to start auto-complete for Gams automatically. But this can be done with M-x auto-complete-mode.
;; ac-modes – major modes ac can run on
(add-to-list ‘ac-modes ‘gams-mode)

;; toggle auto-complete in all buffers

These extensions make Emacs now to a modern text editor.
