can R solve these paired equations
Turn your problem into an optimization one and use the various
optimization abilities of R, for instance have a look at nlm:
?nlm
As an example to solve the rather simple:
x-y=0
x+y=2
We could do:
f <- function(vals) {
x <- vals[1]
y <- vals[2]
sum(c(x-y,x+y-2)^2)
}
nlm(f, c(2,2))
PS: A google search for "rhelp solving nonlinear system of equations"
would likely have given you some starting points.
PS2: Perhaps someone more expert could comment on the differences
between optim, nlm and nlminb.
