Anleitung zur Übung

  • Create a new vertex attribute called 'gender' from the vector genders using set_vertex_attr().
  • Create a new vertex attribute called 'age' from the vector ages using set_vertex_attr().
  • View all vertex attributes using vertex_attr().
  • View the attributes of the first five vertices in a dataframe using V(g)[[]].

Interaktive Übung

Versuche dich an dieser Übung, indem du diesen Beispielcode vervollständigst.

library(igraph)

# Inspect the objects 'genders' and 'ages'
genders
ages

# Create new vertex attribute called 'gender'
g <- ___(g, "gender", value = genders)

# Create new vertex attribute called 'age'
g <- set_vertex_attr(g, "___", value = ___)

# View all vertex attributes in a list
___(g)

# View attributes of first five vertices in a dataframe
V(___)[[1:5]]
