[R] non-linear binning? power-law in R

Why not try to avoid binning (and density plot) at all? An alternative 
could be a qqplot (as a log-log-plot), e.g.

plot(ppoints(length(x4)), x4[order(x4)], log="xy")
abline(lm(log(x4[order(x4)])~log(ppoints(length(x4)))), col="red")

If the assumptions of uniform distribution and power transformation 
y=a*x**b are true, the coefficient of lm estimates the exponent b.
