spread We have designed and constructed an interactive spreadsheet
|
||
|
|
interface to S/Splus that maintains the complete power and
|
||
|
|
generality of the S language. At user level, the interface
|
||
|
|
behaves like the popular spreadsheet programs available for
|
||
|
|
personal computers: one or more S data objects (matrices or
|
||
|
|
three-way arrays) are displayed on the screen. The user
|
||
|
|
graphically (with mouse or cursor motion) identifies a cell
|
||
|
|
for review, and possible updating, of its contents. Macros
|
||
|
|
containing arbitrary S expressions can be associated with
|
||
|
|
the entire spread.frame or one of its cells. The
|
||
|
|
spreadsheet is designed in a modular fashion with
|
||
|
|
device-specific methods for the display and updating of
|
||
|
|
spreadsheet objects. We include methods for two devices:
|
||
|
|
the generic S graphics device and a character based device
|
||
|
|
using the emacs 19 environment.

Setup Instructions
|
||
|
|
|
||
|
|
|
||
|
|
The emacs spreadsheet interface for S consists of four S files
|
||
|
|
"sprd-*.s" and one emacs lisp file "sprd-int.el".
|
||
|
|
|
||
|
|
1. Create a new directory to store the four S files "sprd-*.s" and one
|
||
|
|
emacs lisp file "sprd-int.el". I use "/disk5/rmh/sprd3d/". You might
|
||
|
|
wish to place it under the directory where you store other S/Splus
|
||
|
|
libraries.
|
||
|
|
|
||
|
|
2. Make a new .Data, "/disk5/rmh/sprd3d/.Data", start S/Splus, and
|
||
|
|
source the four sprd-*.s files:
|
||
|
|
|
||
|
|
> source("sprd-emc.s")
|
||
|
|
> source("sprd-grd.s")
|
||
|
|
> source("sprd-spr.s")
|
||
|
|
> source("sprd-txt.s")
|
||
|
|
> q()
|
||
|
|
|
||
|
|
3. The directory /disk5/rmh/sprd3d/ should now be treated as a
|
||
|
|
library directory and should not be further touched. All further work
|
||
|
|
using the spread.frames should be done in a different directory.
|
||
|
|
|
||
|
|
4. See the file sprd3d.how for user instructions. You may look at
|
||
|
|
the file "gradexmp.s" for an example.
