In genalg? I can't get it to work.
The following code works just fine:
GenFit -rbga(Lower, Upper, evalFunc = evaluate)
Lower and Upper are each numeric vectors with 7 elements. Evaluate is an
objective function.
However, when I want to use a suggested chromosome, I get an error message.
My code is
start - c(1,0.1,10, 100,1,100,1)
suggestions - list(start)
GenFit -rbga(Lower, Upper, suggestions = suggestions, evalFunc = evaluate)
The error message is:
Error in 1:suggestionCount : argument of length 0
Thanks.
rbga( c( -1, -1), c( 1, 1), evalFunc= function( string){ sum(
string**2)**0.5}, suggestions=t( as.data.frame( c( 0, 0

Re: [R] suggestions argument in rbga function in genalg package
Enrico,
The idea of looking at the code never occurred to me. That's a great idea which
will come in useful
I'm sure.
In this particular case the using list() or as.matrix() does not solve the
problem, but
those are both good ideas.
Thanks for the reply.

I do not use this package, but a quick look at the code shows this.
if (!is.null(suggestions)) {
# [deleted]
suggestionCount = dim(suggestions)[1]
So 'suggestions' needs to have a dim argument (while the documentation
speaks of an 'optional list of suggested chromosomes'). You could try
as.matrix(c(1,0.1,10, 100,1,100,1))
But I cannot tell if that solves your problem since you have not
provided your objective function (ie, you have not provided the
commented, minimal, self-contained, reproducible code that the footer
of this message speaks about).
