Description
This function uses maximum likelihood to fit a nominated probability
density function to the data of a seedtrap transect holder.
Usage
1
fitDistances(x, family)
Arguments
x
an object of class transectHolder
family
the nominated distribution, which must be one of those
distributions that can be fit by fitdistr of the MASS package.
Value
The function returns the parameter estimates for the nominated family.
