get cells by the combination of their column and row names
Hi,
I have a (correlation) matrix and I want to select a subset of its cells depending on the combination of their column and row names.
This illustrates my problem: mtrx <- matrix(c(1,2,3,4,5,6,7,8,9), nrow=3, ncol=3, dimnames = list(c('c132','c432', 'c233'), c('r132','r233', 'r432')))> mtrx r132 r233 r432c132 1 4 7c432 2

Visualising multiple response contingency tables
Dear R Help Community,
I have a question and an answer (based on reading this forum and online
research), but I though I should share both since probably there's a much
better way to go about my solution. My question is specifically about how
to best visualise multiple response contingency tables. What I mean by
'multiple response' is that the total number of responses per row of a

Subject: compare a vector and a row of a matrix
Date: Sun, 26 Sep 2010 23:23:52 +0800
Hi Everyone:
I am trying to compare a vector and rows of a matrix
for example
> xn <- c(1,2,4,4,5,5,5,6)
>yn <- c(1,2,5,7,1,2,3,1)
>mtrx <- cbind(xn, yn)
when I tried, say, > c (1,4), the result was TRUE, TRUE.

help in lme
To anyone who can help,
I have two stupid questions, and one fairly intelligent question
Stupid question (1): is there an R function to calculate a factorial of a number? That is...is there a function g(.) such that g(3) = 6, g(4) = 24, g(6) = 720, etc?
Stupid question (2): how do you extract the estimated covariance matrix of the random effects in an lme object?

multiple bases to decimal (was: comparing two matrices)
Hi again,
I was contemplating the solution using base 3:
set.seed(3)
mat2 <- matrix(sample(0:2, 15, replace=T), 5, 3)
Extracting the line numbers is simple:
bases <- c(3, 3, 3)^(2:0) # or just 3^(2:0)
colSums(apply(mat2, 1, function(x) x*bases)) + 1
[1] 7 23 25 8 1
The problem is sometimes the columns have different number of levels, as in:
mat1 <- expand.grid(0:2, 0:2,

specification for glmmPQL
Hello All,
I have a question regarding how glmmPQL should be specified. Which of
these two is correct?
summary(fm.3 <- glmmPQL(cbind(response, 100 - response) ~ expt,
data = data.1, random = ~ 1 | subject,
family = binomial))
summary(fm.4 <- glmmPQL(response ~ expt, data = data.2,

smb.conf
I added a hosts deny line to above and denied one specific ip address.
I then deleted that line but added hosts allow and made this equal to any
ip address within previous "denied ip address's subnet. However, the
afore-mentioned ip was still denied and I had to allow it individually.
Can anyone tell me why.
Thanks

[XCP] XCP project suggestions on the wiki
Hi,
I''ve collected together a bunch of XCP-related project suggestions and stuck them on the xen wiki:

The main idea is that new people who want to work on XCP can use this list for inspiration... each idea has a rough guesstimate of size/ knowledge required/ impact and an initial first contact (who either suggested the idea

A general deployment question (OT)
Does anyone have a guesstimate of how many active Asterisk
installations there are? Sorry this is off topic, need it for a
customer proposal and they need comfort on stability. A count of the
downloads from Digium would be a good start but I couldn't find this

Dovecot 2.0 progress?
Hi,
Been having a look at the roadmap on the wiki for Dovecot 2.0 and I was
wondering how that's progressing? Are you able to offer a guesstimate on how
far it is from stable Timo?
Just asking because we're moving to new servers soon and I'm considering
using the opportunity to switch from Dovecot/Maildrop/Maildir to
Dovecot/deliver/mdbox if 2.0 is likely to be reasonably safe to use

yet another vectorization question
Dear R-helpers,
I'm trying to develop a function which specifies all possible expressions that
can be formed using a certain number of variables. For example, with three
variables A, B and C we can have
- presence/absence of A; B and C
- presence/absence of combinations of two of them
- presence/absence of all three

Number of listeners per server box ?
I have a proposal from RackSpace to put icecast on the following

how many listeners each box can support?
Proposed hardware by RackSpace for each server box:
Dual 866 MHz processor
2 GB ECC RAM
100 Mbps connection
I need to know how many listeners can connect to each of these boxes.

millions of comparisons, speed wanted
Dear all,
I have a 10 columns matrix which has 2^10=1024 unique rows, with values 0 and
1.
What I would like to do is a little complicated; in a simple statement, for a
subset (say 1000 rows) I want to perform pairwise comparisons between all
rows, find out which rows differ by only one value, replace that value by
"x", get rid of the comparisons that differ by more than one value
