package relax contains some functions for report
writing, presentation, and programming: relax(), tangleR(),
weaveR(), (g)slider(). "relax" is written in R and Tcl/Tk.
relax creates a new window (top level Tcl/Tk widget) that consists
of two text fields and some buttons and menus.
Text (chunks) and code (chunks) are inserted in the upper text field (report field).
Code chunks are evaluated by clicking on EvalRCode.
Results are shown in the lower text field (output field) and
will be transferred to the report field by pressing on Insert.
In this way you get correct reports. These reports can be
loaded again in cause of presentation, modification and result checking.
tangleR() and weaveR() implement a plain kind of tangling
and weaving. gslider() and slider() are designed to define sliders for interactive
experiments in a simple way.
The syntax rules of code chunks and text chunks are defined by
the noweb system proposed by Norman Ramsey
(http://www.eecs.harvard.edu/~nr/noweb/intro.html).
