Не удается прочитать файл paj как сетевой объект, используя пакет R 'network'

Question

У меня есть несколько сетей Pajek в формате файла.net, но он больше не может быть импортирован с использованием read.paj из сетевого пакета. Он работал под окнами. Может кто-нибудь помочь?

read.paj (file.path) возвращает только NULL

Вывод под debug=True в функции read.paj:

Answer 1

Я не уверен, почему read.paj из "сети" не работает... НО но ты мог попробовать read.graph из пакета "igraph", а затем использовать asNetwork Из пакета "intergraph" получить данные как объект класса network:

library(igraph)
g <- read.graph("z.net", format="pajek")   # that's your file
g

# IGRAPH U--- 19 73 -- 
# + attr: id (v/c)


library(network)
library(intergraph)
net <- asNetwork(g)
net

# Network attributes:
#  vertices = 19 
#  directed = FALSE 
#  hyper = FALSE 
#  loops = FALSE 
#  multiple = FALSE 
#  bipartite = FALSE 
#  total edges= 73 
#    missing edges= 0 
#    non-missing edges= 73 
#
# Vertex attribute names: 
#    id vertex.names 
#
# No edge attributes
