Dear List,
I have an environmental data set with several missing values that I
am trying to relate to a community structure data set using a mantel
test. One solution to the missing data problem seems to be multiple
imputation; I am using the Amelia package. This generates several (five in

Hello all,
I am thinking about applying season::cosinor() analysis to some
irregularely spaced time series data. The data are unevenly spaced, so
usual time series methods, as well as the nscosinor() function are out. My
data do however trend over time and I am wondering if I can feed date as
to something
that works.

Thanks Gavin,
This seems like a promising approach and a first pass suggests it
works
with this data. I can't quite figure out how I would go about
interrogating
the fitted spline to deterine when
. You can't really make much practical
use out of those values are they relate specifically to way the
penalised regression spline model has been converted into an
equivalent linear mixed effect form.

Hello Gavin and R-sig-ecology list,
Based on Gavin Simpson's very helpful advice on this forum, I have
been modelling biotic and environmental parameters using a generalized
additive mixed model of the form
mod - gamm(logit.Area ~ s(DoY, bs = cc) + s(elapsed.days), data = lldata,
anyone have any suggestions?
Thank you for your time.
Sincerely,
Jacob Cram
