Node attributes and subsetting
In this exercise you will learn how to add attributes to vertices in the network and view them.
This exercise is part of the course
Network Analysis in R
Exercise instructions
- Create a new vertex attribute called 'gender' from the vector
gendersusingset_vertex_attr(). - Create a new vertex attribute called 'age' from the vector
agesusingset_vertex_attr(). - View all vertex attributes using
vertex_attr(). - View the attributes of the first five vertices in a dataframe using
V(g)[[]].
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
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]]
