Dear all I'm trying to calculate the number of shared species between sites.
I have a dataframe with in the first column the names of the sites; the names of the other columns are the species names. To use the shared function from the package RICH one needs to input different matrices. So actually, I want to split the dataframe per row so that each row becomes a separate matrix and then perform the shared function. I used split(dataframe, site_name), which splits the dataframe, but I cannot call the separate matrices to calculate the number of shared species.. Does anyone know a way to do this? Or does somebody know a better way of determining this? Thanks!
