rtqc_attenuation(x, threshold, n.obs, ...)
| x | A vector of values. |
|---|---|
| threshold | A length-2 vector specifying "suspect" and "fail" thresholds for the minimum standard deviation of a set of observations. |
| n.obs | The number of observations, including the current observation, to use for calculating standard deviation. |
| ... | Other arguments to pass to |
An ordered factor of test flags of same length as x.
