Mixing matrix cells and margins
Description
attrs
is the rows of the mixing matrix and whose RHS
gives that for its columns (which may be different). A one-sided
formula (e.g., ~A
) is symmetrized (e.g., A~A
). A two-sided
formula with a dot on one side calculates the margins of the
mixing matrix, analogously to nodefactor
, with A~.
calculating the row/sender/b1 margins and .~A
calculating the
column/receiver/b2 margins. If row and column attributes are the
same and the network is undirected, only the cells at or above
the diagonal (where \text{row} \le \text{column}
) will be calculated.
Usage
# binary: mm(attrs, levels=NULL, levels2=-1)
# valued: mm(attrs, levels=NULL, levels2=-1, form="sum")
