[R] [GGplot] Geom_smooth with formula "power"?

[Catarina Silva]

Hi,

It's possible to use ggplot and geom_smooth to adjust a power curve to the
data?

Initially i have done the adjustement with nls and the formula 'a*x^b', but
resulted the singular matrix error for start solution. Alternatively I used
the log transformation and i had correct results, but I can't draw a power
curve on the graphic.

Someone know how to solve this problem?

 

Ty,
