Dear All,
Thanks in advance for any help. I have a square matrix of measures of
interactions among individuals and would like to calculate a values from a
function (colSums for example) with a single individual (row) excluded in
each instance. That individual would be returned to the matrix

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
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

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
one is more appropriate than the
