AIC in bestglm, glm, and lm - why do they differ?
I recently found the "bestglm" package while trolling CRAN for a function to
save some keystrokes with simple (k<10) nested models. I am interested in
using the best of several nested linear models which I have explored using
lm(), glm() and now bestglm(). When I compare the AIC values for the 'best'
candidate model I get the same AIC values with lm() and glm() but a

tricky (for me) merging of data...more clarity
Hi Again,
Thanks very much for your response. It seems my example got rearranged
(transposed?) after I posted it. Hopefully this example will be more
clear. I have one file (ex. sheet 1) that will have a column for
individuals (ind) and a column for the date (date). I would like to merge
this with another file (ex. sheet 2) that has both the 'ind' and date column
as well as associated

permutation/randomization
Hello,
I have what I suspect might be an easy problem but I am new to R and
stumped. I have a data set that looks something like this
b<-c(2,3,4,5,6,7,8,9)
x<-c(2,3,4,5,6,7,8,9)
y<-c(9,8,7,6,5,4,3,2)
z<-c(9,8,7,6,1,2,3,4)
data<-cbind(x,y,z)
row.names(data)<-c('a','b','c','d','e','f','g','h')
which gives:

calculating time interval distributions
Dear List,
I have data on a approximately 100 individuals visiting a a central logging
station over a 1000 times. I would like to be able to calculate the
distribution of inter-visit time intervals for all possible pairs am stuck
on how to code for this. Single pairs are not a problem but extending it
has been difficult for me. So for the toy data below I'd like to calculate

tricky (for me) merging of data
Dear List,
I am having trouble with a tricky merging task. I have one data sheet that
has dates (continuous) that radio collared individuals were monitored via
telemetry. I have a different sheet containing data from instances where
individuals were recaptured and associated body condition data was recorded
(sheet 2). I would like to merge the two sheets by individual and date (I

adding copies of rows toa data frame based upon start and end dates
Hello All and thanks in advance for any advice.
I have a data frame with rows corresponding radio-collared animals (see
sample data below). There is a start date (DATESTART), and end date
(DATEEND), and the number of days on air (DAYSONAIR). What I would like to
do is add a column called DATE to so that each row ID has a row for every
day that the radio collar was on the air while copying all

resampling from distributions
Hello All,
Once again thanks for all of the help to date. I am climbing my R learning
curve. I've got a few more questions that I hope I can get some guidance on
though. I am not sure whether the etiquette is to break up multiple
questions or not but I'll keep them together here for now as it may help put
the questions in context despite the fact that the post may get a little
long.

Estimates of coefficient variances and covariances from a multinomial logistic regression?
Hello and thanks in advance for any help,
I am using the 'multinom' function from the nnet package to calculate a
multinomial logistic regression. I would like to get a matrix estimates of
the estimated coefficient variances and covariances. Am I missing some

Net-talk
I wanted to try and see if I could get my Hawkings Net-Talk USB phone to
work with our asterisk setup via yakaphone. Has anyone ever tried this?
It sees the mic and speakers, but if we could get the keypad to talk
with yaka and in turn with asterisk, that would be really nice.
If there are any other recommendations for a VOIP USB phone that you
could plug into a windows and/or linux machine and

Hello all and thanks in advance for any advice.
I am very new to R and have searched my question but have not come up with
anything quite like what I would like to do.
My problem is:
I have a data set for individuals (rows) and values for behaviours
(columns). I would like to know the proportion of shared behaviours for all
possible pairs of individuals. The sum of shared behaviours divided by

restricted bootstrap
Hello List,
I am not sure that I have the correct terminology here (restricted
bootstrap) which may be hampering my archive searches. I have quite a large
spatially autocorrelated data set. I have xy coordinates and the
corresponding pairwise distance matrix (metres) for each row. I would like
to randomly sample some number of rows but restricting samples such that the
distance between them is

Seeking Collaboration in Development and Validation of an Anomaly Detection System for Asterisk
We are currently doing research and development on an open-source
runtime application monitoring system for Asterisk. This system is aimed
at detecting and mitigating problems or vulnerabilities that arise from
residual errors--whether unintentional or malicious--either in the
application code or in its configuration or usage patterns. It can, for
example, be used to detect and prevent
