I appreciate a simple demonstration > of the above techniques with Splus commands. I do this in two ways. Most commonly, I start editing a file of S commands using S-mode. That is, "C-x C-f plot1.S". If the extension .S has not been added to the auto-mode-alist, you will also have to manually establish S-mode with "M-x S-mode". (StatSci prefers the extension .q for S source code.) I also start an inferior S process using "M-x S". I make sure to call the graphics driver and to turn it off in the file I am editing. (In S this is done by calling graphics.off() - I can't remember how this is done in S-plus). I also do any attachments and detachments of frames or directories I will need. My goal is to leave S in the same state when execution of the file finishes as it was when execution started. The emacs key sequence "C-c C-b" sends the current buffer to the S process. I then use ghostview to view the PostScript file I have created, go back and modify the plot commands, hit "C-c C-b" again, ... until I am satisfied with the plot. If I have not thought ahead and created the plot as a separate file, I can still use cut-and-paste to clip the relevant parts from the S process buffer. Use this to create a file called an S-transcript. The usual extension for the file name is .St and the file should have the mode set to S-transcript-mode. There is a function within S-transcript-mode that will clean up the transcript by removing any prompts or output. The cleaned file can then be stored as S commands and modified as desired. As I recall, S-transcript-mode is not well documented in the texinfo file accompanying the S-mode source. I think you have to do a bit of browsing in the source to find out about it. It does have documentation that can be displayed through "C-h m" (describe-mode). Version 4.5 of S-mode is available as a gzip'd tar file from ftp://wingra.stat.wisc.edu/pub/src/emacs-lisp The designer and author of S-mode is David Smith.
