errors when no complete cases remain after na.omit

Code
  RMitemInfitCutoff(d, iterations = 3, parallel = FALSE)
Condition
  Error:
  ! No complete cases in data. All rows contain at least one NA.

parallel = TRUE without n_cores or mc.cores warns and falls back

Code
  res <- RMitemInfitCutoff(make_dich(), iterations = 4, parallel = TRUE, seed = 1,
  cutoff_method = "quantile")
Condition
  Warning:
  For parallel processing, specify n_cores or set options(mc.cores = N).
  (Use `parallel::detectCores()` to see how many cores are available.)
  Falling back to sequential (single core) processing.
