[R-sig-eco] Package to analyse population time series (trend analysis)

[Philippi, Tom]

Manuel--
The proper package depends entirely on what your data are: how many sites
you collect counts for, whether those sites are a probability sample over
an area or the only locations you are making inferences about (e.g., census
counts), whether those counts have Poisson error, overdispersion (e.g.,
aggregation) or zero-inflation (e.g., extra 0s from bad weather or bad
sites), imperfect detection, marked individuals, whether you expect a
linear or only monotonic trend, whether you have covariates that vary by
year (e.g., annual precipitation or winter NINO3.4), or or other aspects I
haven't yet dealt with.

A bit more information about what you have in terms of data, and about the
questions you are interested within the broad definition of "trend" might
get you informed answers.
