R help - Aug 2014 - Fractal package - FDWhittle - Estimating the Hurst exponent

Hello list,

How would one estimate the Hurst exponent of a time series using the Whittle
method in R?

It looks like the Fractal package has a function called FDWhittle, but this
outputs the "FD Parameter" of a time series and not the Hurst
exponent.

Any help would be greatly appreciated, as I am very much lost.

Thanks.
