Hello Gabor
I try these example, but I obtain some errors.
*First example*
yacas(a * Identity(3))
expression(list(list(a, 0, 0), list(0, a, 0), list(0,
0, a)))
it's ok , but the next command:
PrettyForm(%)
Error in PrettyForm(%) : no applicable method for
PrettyForm
If I make a little
hello
I make a subroutine that give-me a (mathematical)
function in string format.
I would like transform this string into function ( R
function ).
thanks for any tips.

#e.g.
fun_String = -100*x1 + 0*x2 + 100*x3
fun - function(x1,x2,x3){
return(
evaluation( fun_String )
Hello R users...
how to align this Zmat (triangle image) in X axis?
I would like that the triangle's base become in the X
axis and
the triangle's height become in the Y axis
Is there some trick for make this?
Thanks.

I thank François Pinard for your attention
one solution, but
very dirty
very ugly
and ~ 30% of calculations cut loose!
if somebody can give a tip, I thank...

z=1-x-y

Hello All!
How to plot a image ( image function )
with restrictions, like a polygon??
Thanks in advance!

# problem example
x - y - seq(-4*pi, 4*pi, len=27)
r - sqrt(outer(x^2, y^2, +))
image( z )
contour(z, add = TRUE, drawlabels = FALSE)
m=scan()
0.2 0.2
0.8 0.2
for you.
You may have other problems, like too much noise to
find the signals you most care about. However, those
are different from the issue you cited.
hope this helps.
