These functions are S3 generics for various brainGraph-defined
objects.
groups returns the “Group” graph attribute for each graph or
observation in the object.
region.names is a generic method for extracting region names from
various brainGraph objects. These are generally convenience functions.
nregions is a generic method for extracting the number of regions from
various brainGraph objects.
# S3 method for brainGraphList
groups(x)# S3 method for corr_mats

# S3 method for data.table
region.names(object)
nregions(object)
An object
For a data.table, region.names assumes that it contains a
factor column named region.
