[R] nls

[Gregory BENMENZER]

Hello,

I want to estimate parameters of the model y=a/x with x=1:10 and y=3/x.
I tested the NLS function.

Could you tell me why it doesn't converge ?

Regards,

Error in nls(y ~ a/x, start = list(a = 2), control = nls.control(maxiter = 100)) :
        number of iterations exceeded maximum of 100
