Create a function with multiple object as an output
I've seen some questions regarding the output of multiple objects from a
function, however the suggestions all end up suggesting the use of
return(list(result1=result1, result2=result2 , result3=result3)).
How can I return multiple objects that are 2 big to be added to a list?

Retrieve hypergeometric results in large scale
I'm going to use
dhyper(x, m, n, k)
to get a 95% coverage. Let me use an example to explain my problem:
Suppose I have a urn containing 90 red and 10 black balls.
Now I wanna remove 3 from the urn. By the following codes:
m<-90;n<-10;k<-3;
x<-0:3
dhyper(x,m,n,k)
I can obtain the probability that 0,1,2,3 red balls will be removed.

Multivariate hypergeometric distribution version of phyper()
Dear R Users,
I employed the phyper() function to estimate the likelihood that the
number of genes overlapping between 2 different lists of genes is due to
chance. This appears to work appropriately.
Now i want to try this with 3 lists of genes which phyper() does not
appear to support.
Some googling suggests i can utilize the Multivariate hypergeometric
distribution to achieve this. eg.:

EventPublisher (contribution)
I got a lot of great help yesterday on my calendar questions. Makes me
want to post another contribution :-)
This one is called EventPublisher. This was packaged also in Marco
Jaeger''s recent post with his excellent Dialogs (a la Windows), but now
I''ll post it by itself in case someone missed it, and also give a little
explanation for ya''ll.

Simulation with R
An apparatus exists whereby a collection of balls is displaced to the
top of a stack by suction. A top level (Level 1) each ball is shifted
1 unit to the left or 1 unit to the right at random with equal
probability. The ball then drops down to level 2. At Level 2, each
ball is again shifted 1 unit to the left or 1 unit to the right at
random. The process continues for 15 levels and the balls are

optimization challenge
I have a challenge that I want to share with the group.
This is not homework (but I may assign it as such if I teach the appropriate class again) and I have found one solution, so don't need anything urgent. This is more for fun to see if others can find a better solution than I did.
The challenge:

Constrined dependent optimization.
I have an optimization question that I was hoping to get some suggestions on how best to go about sovling it. I would think there is probably a package that addresses this problem.
This is an ordering optimzation problem. Best to describe it with a simple example. Say I have 100 "bins" each with a ball in it numbered from 1 to 100. Each bin can only hold one ball. This optimization is

Calculating conditional mean of large series of experiments
I need to repeat an experiment 1000 times. Each experiment involves randomly
selecting one ball each from two separate bags. Each bag contains 10 balls,
numbered 1, 2, 3, ... , 10. So the probability of selecting any one pair of
balls is equal to all others.
For each experiment, what I need to do is assign a variable A which
represents the maximum number out of the two balls selected; and a

OT Astricon/Digium Beach Ball Mailing
Just an FYI for Digium. I received a mailing today from you guys
which was nice. The price of mailing was ~$1.60 and inside was an
inflatable beach ball.
Cool, but I tried to blow up the beach ball and the the seam where the
part opens to inflate the ball was not connected to the ball
whatsoever, so it went right in the trash.
I wonder if the sick heat had anything to do with it, was mine just

phyper returns 1 if x==k (PR#8499)
Full_Name: Utz J. Pape
Version: 2.2.0

Submission from: (NULL) (141.14.23.12)
If I use phyper and set parameter x equal to k (meaning that all balls I draw
are white) phyper returns 1 which is not (always) correct:

Plurals and synonym lists
I want to correct spelling errors automatically. I have used search in
the past where I can pass an argument through standard search to correct
a word with up to 2 spelling errors for example or do the more Google
like "Did ya mean?". In this case I just want to change it automatically
and search. I am not too interested in specifying the number of
characters it is out by.

[LLVMdev] dist-check implemented
My final foray into the makefiles for a while has been completed. The

But, now LLVM Makefiles have it too.
dist-check does the following:

sane, essentially "make check".
