Fra: [EMAIL PROTECTED] på vegne af francogrex Sendt: to 29-11-2007 22:00 Til: r-help@r-project.org Emne: [R] How can R be used to solve algebra equations? suppose I have this equation: (x^2+y^2+3z^3)/(5*z^2*x^3)=0 and I want to find x in relation to the other variables which actually is: x=sqrt(-3*z^3-y^2) or x=-sqrt(-3*z^3-y^2) Can R give me this expression solution? I know there is uniroot, but here I want the "expression" not the value, because I do not have values for y and z.
