qc_out_remove: Outliers QC

In sapfluxnet/sapfluxnetQC1: Package with functions related to sapfluxnet project data

Description

Outliers detection, substitution and annotation for SfnData objects

Usage

qc_out_remove(sfn_data, k = 25L, t0 = 10L, method = "hampel",
  reverse = TRUE, substitute = FALSE, parent_logger = "test")

Arguments

sfn_data	SfnData object with the site data and metadata
k	window semi-value (integer) for substitution value calculation. See out_hampel_filter for details.
t0	Integer value indicating the number of standard deviations for outlier detection threshold.
method	Character vector indicating the method to use in the outlier estimation: hampel (default), tukey and quantile.
reverse	Logical indicating if in case of k is bigger than the data length (i.e in the extremes of the vector) a reverse replication must be done. Default to TRUE.
substitute	Logical indicating if the outlier subsitution must be made. Default to FALSE.

Details

Outliers for sap flow data and environmental data are located and substituted by the selected method, using the out_hampel_filter function.

Value

a SfnData object as the one provided with the oulier values substituted and the flags slot updated.
