threshold	threshold for number of MADs used to determine outlier. default 3
direction	return TRUE if the value is above or below the outlier cutoff. default "both", samples above and below the threshold are called outliers.

Value

boolean vector indicating which values of the input vector are flagged as outliers

Examples

x <- c(1, 1, 2, 2, 4, 6, 11)
