When I look at this line:
f4 <- pars[1]*pars[2]*pars[3](pars[1]+pars[4])
It appears to my wet-brain interpreter that you are trying to apply a
function par[3] to the argument (pars[1]+pars[4])
When I insert a "*", I then get output but I don't know if it is
correct.

Hi r-users,
I have the following code to solve 4 simultaneous eqns with 4 unknowns using
newton iteration method. But I got the error message:
pars <- c(1.15, 40, 50, 0.78)
newton.input2 <- function(pars)
{ ## parameters to estimate
alp <- pars[1]
b1 <- pars[2]
b2 <- pars[3]
3 matches
