Hi all:

 

I'm looking for a package that similar to solver in MS. All I need is find a
r to satisfy R0=sum( r * Xt ), where t are from 1 to n and Xt are come from
another formula.

The most package I found were to max or min the obj. function. Is there any
package can do it?

Thanks.

      Peter
