[R] power function fitting

I would like to fit a power model of type: y=b*x(^z) to my data (having y as the response and x as the predictor variables). I could not use linear models like y~x since R should estimate the parameter z and not only the coefficient b. Thus I need a package and a function! Any suggestions? Thanks D
