rtqc_attenuation: Attenuation Test

In mkoohafkan/wqptools: Outlier Detection Working Group Toolbox

Description

Perform a signal attenuation test. For more information see U.S. Integrated Ocean Observing System, 2015. Manual for Real-Time Quality Control of In-situ Temperature and Salinity Data Version 2.0: A Guide to Quality Control and Quality Assurance of In-situ Temperature and Salinity Observations. 56 pp. DOI: 10.7289/V5V40SD4.

Usage

rtqc_attenuation(x, threshold, n.obs, ...)

Arguments

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 stats::sd(), i.e., the argument na.rm.

Value

An ordered factor of test flags of same length as x.

Examples

fake.data = sin(seq(0, 10, by = 0.1) * pi) * seq(10, 0, by = -0.1)
rtqc_attenuation(fake.data, c(1, 0.5), 10)
