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 reliance on
Excel for nearly everything else).

so anyway, what I'd normally do is take a set of data like this:

 pH counts  3.8 968  5.0 1347  5.8 2867  6.6 9203  7.0 15817  7.4 20297  8.2
31916  9.2 35756
then fit this to a Boltzman sigmodial in Graphpad. Graphpad spits out a
much longer set of vectors and also information about v50 and confidence
intervals etc (if anyone is familiar with that software). This is what i'd
like to replicate.

It might be that I just don't know what i'm doing,so feel free to call me
an idiot but any help is greatly appreciated!
