Marking networks formats
Description
These functions implement logical tests for various network properties.
All is_*()
functions return a logical scalar (TRUE or FALSE).
-
is_twomode()
marks networks TRUE if they contain two sets of nodes. -
is_weighted()
marks networks TRUE if they contain tie weights. -
is_directed()
marks networks TRUE if the ties specify which node is the sender and which the receiver. -
is_labelled()
marks networks TRUE if there is a 'names' attribute for the nodes. -
is_attributed()
marks networks TRUE if there are other nodal attributes than 'names' or 'type'. -
is_signed()
marks networks TRUE if the ties can be either positive or negative. -
is_complex()
marks networks TRUE if any ties are loops, with the sender and receiver being the same node. -
is_multiplex()
marks networks TRUE if it contains multiple types of ties, such that there can be multiple ties between the same sender and receiver. -
is_uniplex()
marks networks TRUE if it is neither complex nor multiplex.
