I'm trying to fit a power law distribution to some sample data. I am trying to find xmin using the estimate_xmin() function. Does anyone know why I get an error about attempting to apply a non-function? 

abs.logreturns <- as.data.frame(t(abs.logreturns))
x <- abs.logreturns
estimate_xmin(x, xmins = NULL, pars = NULL, xmax = 1e+05, distance = "ks")

Error message:

Error in m$getDat() : attempt to apply non-function

You can't pass a vector to the estimate_xmin() - it needs to be a powerlaw object. See the Getting Started and/or Worked examples vignettes in the poweRlaw package - https://github.com/csgillespie/poweRlaw
