  df,
  checkCols = NULL,
  comparison = `==`,
  step = NULL,
  verbose = FALSE
)

Arguments

df	A dataframe
checkCols	A character vector with exactly two strings. The first names the grouping variable, and the second, the accompanying _numeric_ sequence variable.
comparison	A relational operator for the check, with back-ticks.
