[R] Help with SSlogis and nls

[Mahometa, Michael J]

Hi,

I'm trying to use SSlogis to fit a logistic model, but I get the error:
"step factor 0.000488281 reduced below 'minFactor' of 0.000976562"

I know I can use the nls.control within nls to help with this error, but the nls call that is producing this error looks to be from _within_ SSlogis. So my question is:
How can I use nls.control for influencing the nls call within SSlogis?

Thanks,
Michael
