How I count the all possible samples??
Dear Members,
I am facing a problem during counting a sample.
I have 4 characters i.e. A,C,G,T of DNA sequence and code this sequence by 1,2,3,4 respectively.

H1,H2,H3....upto H7?
if there is any function or any package in
which i can find this entropy directly. do you have any information
please share this and i will be very thankful to you.

Solving graph theory problems with R ? (minimum vertex cover)
I just realized (after many discussion with friends), that I might need to
solve a (classical) graph theory problem with R.
My specific problem is called:
Minimum vertex cover <http://en.wikipedia.org/wiki/Vertex_cover#Definition> for
a hypergraph <http://en.wikipedia.org/wiki/Hypergraph> (Please see the links
for a formal explanation, also with some pictures)

Rx/Tx fine tuning of analogue card to PRI card - Am I right with my theory?
Hi Everyone,
I want to fine tune the Rx and Tx gain on an analogue Sangoma card by
dialing into another server that is running on Sangoma PRI card (both
services on Bell network).
[mwatt1004khz]
exten => s,1,Answer
exten => s,n,PlayTones(1004/1000)
exten => s,n,Wait(300)
If I match the Rx/Tx numbers on both sides by monitoring "ztmonitor X -vv"
am I right with my theory of

Sampling theory
Hi there,
are there any R-packages for computations required in sampling theury
(such as confidence intervals under random, stratified, cluster sampling;
I'd be partoculary interested in confidence intervals for the population
variance, which is difficult enough to find even in books)?
Thanks,
Christian

Nash equilibrium and other game theory tools implemented in networks using igraph or similar
Why don't you implement and uplad the package to CRAN?

kernel + klibc tree now, in theory, feature-complete
I have updated and pushed the klibc-kernel tree. "In theory" it should
be a 1:1 replacement for any stock kernel, which kinit taking up the slack.
Anyway, I haven't yet removed any in-kernel functionality, but that's
hopefully coming; the in-kernel functionality won't be executed in
either case.

[LLVMdev] [LLVMDev] [Register Allocation Theory] Is register allocation indeterminate?
Has anyone read anything about register allocation being
indeterminate? I have seen much literature about "optimal register
allocation," but does anyone know a case where it is not?

bonding theory question
Hello All,
I am currently using bonding with 2 NICs (using mode 0). Its been
working well, but I am trying to understand how it works (I am a total
newbie).
mode=0 (balance-rr)
Round-robin policy: Transmit packets in sequential order from the
first available slave through the last. This mode provides load
balancing and fault tolerance.
So I have 2 NICs (1 NIC attached to switch A, 2nd NIC

Multiple server theory
3 computers...
- WinNT4 - presently PDC-soon BDC - some file serving - print serving -
AV server
- Linux 1 - presently joined to domain - slave DNS/LDAP - primary file
server - primary SMB HOME/PROFILES and SHARES
- Linux 2 - presently BDC-soon PDC - web & mail server - master DNS/LDAP
- DHCP server
Should I be running winbind on Linux 1?
Does Samba 3.0.0 with LDAP obviate the need to fix

Item Response Theory
Hi,
I work with a medical education company and we are interested in
implementing item response theory for our question bank. A few packages for
this already exist in R. We are looking for an expert R developer to
facilitate the implementation with our data. This would be an ongoing
relationship for a part-time consultant. Please respond with a resume/CV
and your availability.
Thanks,

(Off topic.) Game theory.
This has nothing to do with R as such; I'm simply trying to exploit
the vast resource of knowledge and expertise that resides in the R
community.
For my sins, I am teaching a course on Game Theory this term. Game
Theory I know from ***nothing***. I am trying to learn the subject
as I go along, staying perhaps half a step in front of the students.

differential item function for item response theory
Hi my friends,
I'm very new to R and need your help.
I used R and ltm package for item response theory (IRT) modeling.
I also need to compute differential item function (DIF) for IRT
models. I searched the archive but basically found nothing.
Could you help me find some sources about handling DIF of IRT?
Many thanks in advance!

Evidence Theory in R
Hello,
well, I searched list-archive, cran and the references, but found
nothing. Thus:
Does anybody around here know anything about Dempster-Shafer Theory,
Evidence Theory or Hints in R? Has anybody stumbled about a package that
I overlooked or implemented something in this area? I really would like
to not implement a hint-model a second time.
My apologies if I missed something obvious, but I
