I have just started using manyglm to analyze nematode with associated

algorithm works. I have a question about the adjusted p- values. I
pairwise comparison for one of my factors but the p-values generated
all the same for each pair of comparison. Is this output normal?
are the p-values adjusted when running the pairwise comparison? Which

Below is the script I used.
Thanks and hoping to hear from you soon

You can look for local data on GBIF too.

Thank you very much Rich.
Yes, you are right, is a very broad spectrum.
I teach mainly to wildlife ecology students.
I was using several datasets from different sources for homeworks
final projects, but some of the students were "sharing" the results
assignments so I decided to assign different datasets to each
their homeworks. This means that I need several datasets for each
assignment, and the data need to be similar in the structure, for
logistic regression, the response variable needs to be binary, and

Ecology, and it's applied focus Environmental science, are very
been working with these data for several decades so I need to ask
types
of data you want.
I don't know what's available from Costa Rican agencies but I do
in the US you can get geochemical, biological, hydrologidal, and
from the US Geological Survay, Environmental Protection Agency
not removed them), Department of Agriculture's Forest Service and
Resources Conservation Service.
You can also look at StreamNet run by the Pacific States Marine
Council, The Army Corps of Engineers for hydraulic, flow, and
transport data.
That's a start.
