# 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]]
