interactions among individuals and would like to calculate a values from a

each instance. That individual would be returned to the matrix befo

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
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

I am not clear how, in practice, the multinom() function in nnet and the

understand that they are fit differently. Are there certain scenarios where

Hello list,
Thanks in advance for any help.
I have many (approx 20) files that I have merged. For example

m1 <- merge(d1, d2, by = c("IND", intersect(colnames(d1), colnames(d2))),

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

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
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

My problem is:

(columns). I would like to know the proportion
