[R] Newbie Question: Shifted Power Fit?

[Panagiotis G. Ipeirotis]

Hi,

I am completely new to R and I feel kind of lost.
Although I can accomplish most of the basic taks,
I am very confused when I am trying to do the 
following:

I have multiple sets of 2D data that are coming from
distributions of the form:

y = A(x-C)^B     (Eq.1)

I am trying to estimate for each set the best values 
of A, B, and C so that Eq.1 will be the best fit for
the data. I guess that it should be easy to do, but
I lack the experience :(

I would appreciate any help on this.

Thanks,
Panagiotis
