Hello again. Now I have the following:

expression(list(R == 100 * (1 - 2 * y/10000)))
Try the Ryacas Sym interface:
library(Ryacas)
R <- Sym("R")
y <- Sym("y")
ans <- Solve(R == 100 * (1 - 2 * y / 10000), R)
ans
expression(list(R == 100 * (1 - 2 * y/10000)))
Set(y, 3)
expression(3)
ans
expression(list(R == 4997/50))
Set(y, 4)
expression(4)
ans
expression(list(R == 2498/25)) -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com
