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
