R help - Jul 2007 - about stableFit() and hypFit() of fBasics package

Dear R users,

I'm trying to fit stable distribution and hyperbolic distribution to my data
using stableFit(), and hypFit() of fBasics.
However, there are some problems

This is the result
=====================================> stableFit(lm, alpha = 1, beta = 0,
gamma = 1, delta = 0, doplot = TRUE, trace = FALSE, title = NULL, description =
NULL)
Title:
 Stable Parameter Estimation 

Call:
 .qStableFit(x = x, doplot = doplot, title = title, description = description)

Model:
 Student-t Distribution

Estimated Parameter(s):
alpha  beta gamma delta 
   NA    NA    NA    NA 

=====================================
first, this is stable distribution, but in "Model", it's always
Student-t Distribution.
Second, everytime I run stableFit(), the result of Estimated Parameter(s) is NA.
I can't really find what's wrong in my code.

In the case of hyperbolic distribution, this is the result
=====================================
Model:
 Hyperbolic Distribution

Estimated Parameter(s):
    alpha      beta     delta        mu 
63.201132  1.991194 11.165716  2.921906 

There were 41 warnings (use warnings() to see them)

Warning messages:
1: NA/Inf replaced by maximum positive value
2: NA/Inf replaced by maximum positive value
...........................................

=====================================First, I don't what the warning
messages mean and why they appeared.

Many thanks in advance
