summary method for NMdata objects
# S3 method for NMdata
summary(object, ...)An NMdata object (from NMscanData).
Only passed to the summary generic if object is missing NMdata meta data (this should not happen anyway).
A list with summary information on the NMdata object.
The subjects are counted conditioned on the nmout column. If only id-level output tables are present, there are no nmout=TRUE rows. This means that in this case it will report that no IDs are found in output. The correct statement is that records are found for zero subjects in output tables.
