Allow the user to decide whether to ordinate the null matrices
independent on the ordination of the empirical interaction matrix. Gives
a bit more flexibility.
metacom 1.5.2
Order the null matrices for Coherence, and allow option to order
them for turnover calculation. Not ordering nulls for Coherence results
in erroneous positive coherence.
metacom 1.5.1
Do not ordinate the null matrices. This won’t affect the results
from fixed-fixed null.
metacom 1.5.0
Implemented the original null model for turnover as outlined in
Leibold and Mikkelson 2002. Previous versions used a more traditional
null model approach than shifting species filled ranges across sites as
a block. There are pros and cons to both methods, but now the user has a
choice.
