getAttrStatus(graph, pattern = "^miriam.")

getAttrNames(graph, pattern = "")

getAttribute(graph, attr.name)

setAttribute(graph, attr.name, attr.value)

rmAttribute(graph, attr.name)

Arguments

graph

An annotated igraph object.

pattern

A regex experssion representing attribute name pattern.

attr.name

The attribute name

attr.value

A list of attribute values. This must be the same size as the number of vertices.

Details

NetPathMiner stores all its vertex annotation attributes in a list, and stores them collectively as a single attr. This is not to interfer with graph_attr_names from igraph package. All functions here target NetPathMiner annotations only.

Value

For getAttrStatus, a dataframe summarizing the number of vertices with no (missing), one (single) or more than one (complex) attribute value. The coverage

For getAttrNames, a character vector of attribute names matching the pattern.

For getAttribute, a list of vertex annotation values for the query attribute.

For setAttribute, a graph with the new attribute set.

For rmAttrNames, a new igraph object with the attibute removed.
