print output is stable

Code
  print(bart_cor)
Output

  v The Bartlett's test of sphericity was significant at an alpha level of <num>.
  These data are probably suitable for factor analysis.

  χ²(153) = <num>, p < <num>

Code
  print(bart_rand)
Output

  x The Bartlett's test of sphericity was not significant at an alpha level of
   <num>.
  These data are probably not suitable for factor analysis.

  χ²(6) = <num>, p = <num>

Code
  print(bart_na)
Output

  ! The Bartlett's test of sphericity did not render a result.
  The Bartlett multiplier N - 1 - (2p + 5)/6 is not positive for a sample this
  small relative to the number of variables.

  χ²(NA) = NA, p = NA

Code
  print(bart_null)
Output

  ! The Bartlett's test of sphericity did not render a result.
  The Bartlett multiplier N - 1 - (2p + 5)/6 is not positive for a sample this
  small relative to the number of variables.

  χ²() = NA, p = NA
