Hi to all
OK as I did not get any response and I really need some insight I try
again with different subject line
I have troubles with correct evaluating/structure of nls input
Here is an example
# data
x -1:10
y -1/(.5-x)+rnorm(10)/100
# formula list

It is not very clear what you are trying to do here, and
form - structure(list(a = list(quote(y ~ 1/(a - x)), list(a=mean(y,
.Names = a)
is using a historic anomaly (see the help page).
I am gussing you want to give nls an object containing a formula and
an expression for the starting
Thank you
It was simplified version of my problem. I want to elaborate a function
which can take predefined list of formulas, some data and evaluate which
formulas can fit the data. I was inspired by some article in Chemical
engineering in which some guy used excel solver for such task. I was
