hi: could someone please point me to a function that allows me to
solve general non-linear functions?
> irr.in <- function(r, c1, c2, c3 ) { return(c1+c2/(1+r) +
c3/(1+r)^2); }
> solve.nonlinear( irr.in, -100, 60, 70 );
0.189
If someone has written an irr function, this would be helpful,
too---though not difficult to write, either. thanks for any pointers.
Regards,
