#' assertr: Assertive programming for R analysis pipeline.
#'
#' The assertr package supplies a suite of functions designed to verify
#' assumptions about data early in an analysis pipeline.
#' See the assertr vignette or the documentation for more information \cr

#' # - that the column for 'miles per gallon' (mpg) is a positive number
#' # - that the column for 'miles per gallon' (mpg) does not contain a datum
#' # that is outside 4 standard deviations from its mean, and

#' # respectively) contain 0s and 1s only
#' # - each row contains at most 2 NAs
#' # - each row's mahalanobis distance is within 10 median absolute deviations of
#' # all the distance (for outlier detection)
