R- Fisher Information

Dear All,
Can you help me, with the code below how do I obtain the fisher  
information from it.

A modest amount of searching the archives (which is really your  
responsibility):

search.r-project.org/cgi-bin/namazu.cgi?query="fisher 
+ 
information 
"+ 
optim 
&max 
= 
100 
&result 
= 
normal 
&sort 
=score&idxname=functions&idxname=Rhelp08&idxname=Rhelp10&idxname=Rhelp02

... produces:

http://finzi.psych.upenn.edu/R/Rhelp02/archive/72856.html

You should go through the rest of that thread because there is other  
usefull inofrmation in it.

Is my q<-replicate(1000,x) the right way to do simulation.
thank you.

x<-rweibull(100,0.8,1.5)
q<-replicate(1000,x)

I doubt that is what you want. Did you even look at what it produced?

 > x<-rweibull(100,0.8,1.5)
 > q<-replicate(2,x)
 > str(q)
  num [1:100, 1:2] 2.1528 1.8345 5.3473 0.3728 0.0434 ...
 > q[1,]
[1] 2.152798 2.152798
