Dear Prof Carlson,
Thank you for your reply. I'm using 'vegan' with 'vegdist' and 'bray'. I have a
selection of datasets that cover different time periods (converted to
z-scores), so a record that start
useful to
know if the missing values are concentrated in particular rows or columns so
that eliminating a few rows and columns could substantially reduce the
percentage of missing values.

Yes, sorry for the mistake.

For the benefit of other novices, used the following command to read the
documentation:
?coef
Then tried and obtained:
> cvalue100<-coef(graphmodelp~100)
> cvalue100
NULL
Then looked at the model

There is a bug in R 3.4.3(kite-eating tree) in mac os x 10.13.3. If a script
