plot with power law line function

[anvar sour]

Hi there,

I do appreciate if someone kindly help me that enables me to perform
fitting power-law line between two variable. I have two variable (LnB and
LnC), I want to plot this two variables and then I want to fit regression
line with power-law function across this two variable. Is it possible to
use geom-smooth to adjust a power-law curve?

Thanks for the help in advance.
Best Regards,
Anvar,

just use the nls() function, in which specify the model (power law
function) u use. And below is a link to a post talking about non-linear
fitting.

Dear Bin Wang,

thanks for your attention, but how I can calculate "a", and "b" for my data
in the following code?
nlm <- nls(Biomass ~ a * I(Coverage^b), start = list(a = ......, b = ......),
data=data)
plot(Biomass ~ Coverage, data=data)
lines(data$Coverage, fitted(nlm), col = "red", lwd = 2)

Best Regards,
Anvar,
