[R] Symbolic computation in R-solving system of equations

[Søren Højsgaard]

Ryacas provides an interface to yacas from R. So my suggestion is to search the web to see if yacas can solve your specific problem.

Subject: [R] Symbolic computation in R-solving system of equations

Hi,

   To my knowledge, Ryacas can do symbolic computation in R, like Mathematica or Maple.

   I wonder if it (or any other R package) can solve symbolically a system of equations? I have a system of four equations in four variables (non-linear, but not very hard to solve) and wonder if Ryacas or any other package can do it. I do not find the solution in Ryacas. Can it find a symbolic solution to a linear system?

   Thanks,

Miao
