rword2vec, R session aborted

Hello, 

I just installed rword2vec, but the session was aborted when I tried to use it. My code is below. Although this question has been asked before, this issue still remained unsolved. Could you please help on this issue? 

library(rword2vec)
model <- word2vec(
  train_file = "text8",
  output_file = "vec.bin",
  binary=1,
  num_threads=3,
  debug_mode=1)
