Dear R People:
Here is a function to minimized:
mfun1
function(x,a) {
x[1] <- a[1]*x[2] + a[3] - a[2]*(a[1]-a[2])*a[3]
x[2] <- a[1]*x[1] - a[2]*a[3]
return(x)
}Here is my first try:
nlm(mfun1,c(1,1))Error in f(x, ...) : Argument "a" is missing, with no default
nlm(mfun1,c(1,1),a=c(0.8,0.5,1))
Error in nlm(mfun1, c(1, 1), a = c(0.8, 0.5, 1)) :
invalid function value in 'nlm' optimizer
I am stumped. I'm sure that it's something really small that I'm overlooking.
Thanks in advance for any help.
