Need to replicate Boltzman Signmodial Curve fit from Graph Pad
Hello useRs (please don't kill me),
I've fairly new to R having only a few months of playing around with R.
What little I've learned has been extremely useful.
If someone could point me as to how to replicate the Boltzman Sigmodial
curve fit as provided by Graphpad software I'd be eternally grateful.
Where we currently use Graphpad for only this one function,its seems
highly inefficient for a $100 piece of software to be used for only one
function (which isn't nearly as bad as the company's pandemic re...

Estimate Slope from Boltzmann Model (package: DRC)
Dear R Community,
I am using the package DRC ( to fit a boltzman model to my data. I
can fit the model and extract the lower limit, upper limit, and ED50
(aka V50), but I cannot figure out how to get the slope of the curve
at ED50. Is there a simple way to do this? I've searched the mailing
list and looked through the package documentation, but could not...
