Marking networks nodal formats

Source: R/mark_format.R

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_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_egonet() marks networks TRUE if it is a list of networks where each network contains only one node and its ties.
