create a pairwise coocurrence matrix
Hi all,
I am trying to construct a pairwise coocurrence matrix for certain terms
appearing in a number of documents. For example I have the following table
with binary values showing the presence or absence of a certain term in a
document:
term1 term2 term3 term4 term5 doc1 1 1 0 0 1 doc2 1 1 0 1 1 doc3 1 0 0
0 1
And I want to have a matrix with the number of the pairwise coocurrencies.
So,

Hyphenated terms
I am having a problem with any terms which contain hyphens in them. Is
there a particular reason why this wouldn''t work? i''m using aaf, and
have tried with the the previous version (pre 0.10.0) and the newest
versions of both ferret and aaf. Basically, the problem is that
term1-term2 is something my users want to search for, and it appears in
the titles of publications,

Searching different fields based on document permissions
I''m currently writing a system that stores user-created documents. Each
user belongs to a specific group, and the system supports multiple
groups. The thing is, my users want to be able to hide pieces of a
document from other groups. So for example, lets say Joe of team A has
written this document:

nls segmented model with unknown joint points
Hello,
I am interested in fitting a segmented model with unknown joint points
in nls and perhaps eventually in nlme. I can fit this model in sas (see
below, joint points to be estimated are a41 and a41), but am unsure how
to specify this in the nlm function. I would really appreciate any
suggestions or example code. Thanks a lot. -andy

Dirichlet surface
Dear list members,
I want to draw surfaces of Dirichlet distributions with different
parameter settings.
My code is the following:
#<begin code>
a1 <- a2 <- a3 <- 2
#a2 <- .5
#a3 <- .5
x1 <- x2 <- seq(0.01, .99, by=.01)
f <- function(x1, x2){
term1 <- gamma(a1+a2+a3)/(gamma(a1)*gamma(a2)*gamma(a3))
term2 <- x1^(a1-1)*x2^(a2-1)*(1-x1-x2)^(a3-1)

Integrate() error message, I am at a loss
Hello!
I have a problem with integrate() in my function nctspa(). Integrate
produces an error message "evaluation of function gave a result of
wrong length". I don't know what that means. Could anyone suggest me
what is wrong with my function?
These are the examples of function calls that work OK:
nctspa(a=1:10,n=5)
nctspa(a=1:10, n=5, mu=2, theta=3, renorm=0)

[nbdkit PATCH] server: Saner filter .close calls

Simplify iterative programming
Dear,
I am looking for the simplification of a formula to improve the
calculation speed of my program. Therefore I want to simplify the
following formula:
H = sum{i=0..n-1 , [ sum {j=0..m-1 , sqrt ( (Ai - Bj)^2 + (Ci -
Dj)^2) } ] }
where:
A, C = two vectors (with numerical data) of length n
B, D = two vectors (with numerical data) of length m
sqrt = square root
Ai = element of A with index

little fighter 2 vdragonballz 3.0 mod crashes on load sprite
I was trying to run one of my kids favourite games with Wine, alas it crashes accessing a null pointer, early on while loading one of the sprite files (not corrupted). I guess the program should be doing better memory checking but since this works on Windows, maybe Wine has fed him before some broken data.
Unfortunately, the terminal output doesn't seem much helpful:

calibration/inverse regression?
I wonder if anyone out there has written a routine to solve the simple
linear calibration problem?
- fit regression of y vs x
- estimate the value x0 (with 95% CI) that gives y0
Thanks for any help.

question on nbdkit shutdown behavior
I'm observing a difference in timing on nbdkit shutdown that is
dependent on client behavior, and I wonder if that's a bug, but I can't
figure out where to patch it.
When there is no connection present, sending SIGINT to nbdkit terminates
immediately.
If, on the other hand, there is a single client currently connected, the
termination behavior on SIGINT depends on what the client has

When are search indexes updated?
I noticed that occasionally searching in my huge archive mailbox can be
really slow, so I tried doveadm index on it and it seemed to do a lot of
work, which seemed strange given, for example, that dovecot-lda says it
keeps Dovecot index files up-to-date. Then I thought, "maybe these are
different files than the search indices." If so, that's not entirely
clear from the docs and

Help with optimization using GENOUD
Dear Friends,
I have been trying to learn how to use the derivative free optimization algorithms implemented in the package RGENOUD by Mebane and Sekhon. However, it does not seem to work for reasons best described as my total ignorance. If anybody has experience using this package, it would be really helpful if you can point out where I'm making a mistake.
Thanks in advance
