My example code is:

I think the problem lies in the mixture model. First, why do you have two
free parameters p and q. Shouldnt that be p and (1-p)? Secondly, I am not
sure that your data, d2, is compatible with a binary mixture model. It seems
like a sensible binary mixture model cannot be fitted for your data.
OOPS! Sorry, I made an oversight in the code I posted just now
(and I didn't check the result carefullt enough ... ).
The line which was A$Count - as.numeric(A$Count) should have
been A$Count - as.numeric(levels(A$Count)) (i.e. I overlooked
that A$Count as first constructed is a *factor*)!

Hello,

OPPS^2!! Did it again. The version given below now does seem to work
properly: last line now changed (yet again) to
A$Count - as.numeric(levels(A$Count)[unclass(A$Count)])

strsplit should work for your example...

Hi All,
I'm trying to do the following constrained optimization example.
Maximize x1*(1-x1) + x2*(1-x2) + x3*(1-x3)
s.t. x1 + x2 + x3 = 1
x1 = 0 and x1 = 1
x2 = 0 and x2 = 1
x3 = 0 and x3 = 1
which are the constraints.
I'm expecting the answer x1=x2=x3 = 1/3.
I tried the constrOptim function in R

Your initial value is indeed infeasible, as the error message says. Your
x[1] is 1.4, which is not in the interval [0,1].
To incorporate both equalities and inequalities (linear or nonlinear), you
could try my function `constrOptim.nl'. Contact me off the list if you are
interested.
Ravi.
