Question on Variabeles

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
R is not an algebra system but a system for numerical computations. You can write a function that represents (i.e. generates and returns) your matrix and uses its arguments to fill different elements of that matrix. Best wishes, Uwe
