[R] how to fit a curve of form Y = X^Z

I have a question about R, and will be very grateful for any help.
I have two variables X and Y, and think that Y is related
to X by a function of the form : Y = X^Z, where Z is < 1. 
However, I'm not sure how to find the best-fit equation to
fit my data to a curve of this form using R. Have you any ideas?
