I have bunch of pajek networks in file format .net, but it can not be imported using read.paj from network package any more. It was working under windows. Can someone give a hand?
read.paj(file.path) return only NULL
The Output under debug=True in read.paj function:

I'm not sure about why read.paj from "network" does not work... BUT but you could try read.graph from package "igraph" and then use asNetwork from package "intergraph" to get the data as an object of class 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
