ok. sorry for being blurry.
I have x,y data, that probably fits a asymptotic curve (asymptote at N).
now I want to fit a curve onto the data, that gives me the N. therefore
I thought to fit an e-function, namely N(1-e^(y/x)) onto the data and
get the N from the fitted curves' equation.
in the course of this, I was looking for a R-function to fit a given
function to data.
(I believe there is some implementation in MatLab for this kind of
question, anyhow, I wanted to look in R as well...)
I am not an expert, so excuse my misuse of terms. I hope my problem
graspable...?
cheers,

hello,
I want to fit a curve to a simple x,y dataset - my problem is, that I
want to fit it for the following term:
n(1-e^x/y) - so I get the n constant for my data...
Not an R problem in the first place, but the question arises what
"n(1-e^x/y)" means, its is just some scalar value so far. I am looking
for some equation ...

can anyone help/comment on that?
cheers,
