I have a problem about catch the value from function.
I have following two functions (part):

You can have a look at

There are at least 2 ways to solve your problem

Just a further point of clarification: W. E. Deming said there is no
true value to any number obtained as a result of a measurement. If you
change the method of measurement, you will tend to get different
numbers. This introduces the theory of operational definitions.

For the hell of it I grepped my r-help date headers for the last month

The data is:

The traffic looks something like:
The nice thing about the uniform density is that it's easy to know what the
expected pdf(pmf) should look like, namely each observation should have
probability 1/n. That means you can use qqplot. See ?qqplot
Here's an example, using my.data.

you could try 'help.search(aparchFit)'
Something like

Hi,
Can anyone if R has any package that will generate numbers from g-and-h and

but span more of the kurtosis and skewness plane. Any help will be greatly
