outfile is space delimited rather than tab delimited

Hello Vivian,

I found the output file by scImpute is space delimited rather than tab delimited when I specify outfile='txt'

My full scimpute call:

scimpute(count_path, infile = "txt", outfile = "txt", type = "count",
  out_dir, labeled = TRUE, drop_thre = 0.5, Kcluster = NULL,
  labels = labels$cell_type, genelen = genelen, ncores = 8)
