| sits_envelope {sits} | R Documentation |
This function computes the envelope of a time series using the streaming algorithm proposed by Lemire (2009). This functions calls 'dtwclust::compute_envelope' function.
sits_envelope(data = NULL, operations = "UULL", bands_suffix = "env")
data |
A tibble with time series data and metadata. |
operations |
A character sequence for the sequence operations. ("U" for upper filter, "L" for lower filter). |
bands_suffix |
Suffix of the resulting data. |
A tibble with filtered time series values.
