[R] Indicator Species analysis; trouble with multipatt

[Jim Lemon]

Hi Ansley,
Without your data file (or a meaningful subset) we can only guess, but
you may be trying to define groups on the columns rather than the rows
of the data set. Usually rows represent cases and each case must have
a value for the grouping variable.
