I fear that you are looking for a symbolic algebra system, and R is
not that sort of platform. If I am correct and you still want to
access a symbolic algebra system from R, then you should look at YACAS
and the interface to it, Ryacas.

Hi everyone,
Im quite new to R an I have the following Question:
I would like to define Variables which I can add and multiply etc.
and that
R can simplyfy the terms.
The variables should stand for integers.
For example I would like to have an entry in an array with
variable z
and if I add b+z the field should now contain 2z+b. Or if
the field
contains 1 and I add z the field should contain 1+z.
How can I solve this problem?
I tried to set z=integer and then for example matrix[1,1]=i
But this does only work if I assign a value for z first.
I am very grateful for any help.
Thank you very much!
David
