[R] Fitted Value Pareto Distribution

I would like to fit a Pareto Distribution and I am using the following codes. 

I thought the fitted (fit1) should be the fitted value for the data, is it
correct? As the result of the "fitted" turns out to be a single value for
all. 

fit=vglm(ycf1 ~ 1, pareto1(location=alpha), trace=TRUE, crit="c") 
fitted(fit) 

The result is 
fitted(fit)
            [,1]
 [1,] 0.07752694
 [2,] 0.07752694
 [3,] 0.07752694
 [4,] 0.07752694
 [5,] 0.07752694
 [6,] 0.07752694
 [7,] 0.07752694
 [8,] 0.07752694
 [9,] 0.07752694
[10,] 0.07752694
[11,] 0.07752694
[12,] 0.07752694
[13,] 0.07752694

Could anybody give me some advice?
