Hi,
I would like to build a species accumulation curve using specaccum function in R vegan package.
The entry table should be a classic community table species by sites. However, instead of sites, I would use subsequent surveys in a given study area (conducted with the same methodology) and incident data (presence/absence). Is this supported? And, more relevant, do you think this has a theoretical support? References welcome.
Trying to answer this question, I came across iNEXT package that allows incident data. I have still the same doubt about sites/surveys.
What is the most flexible and performing of the two functions?
