gfGapLength | R Documentation |
This is a function taken from Julendat to identify gap lengths in (eco-)climatological measurement series of a given parameter.
gfGapLength(
data.dep,
pos.na,
gap.limit,
end.datetime = Sys.Date(),
units = "days",
...
)
data.dep |
Object of class |
pos.na |
Numeric. Indices of missing data points. |
gap.limit |
Numeric. Maximum length of a measurement gap. All gaps exceeding this threshold will not be considered. |
end.datetime |
Object of class |
units |
Character. Measurement interval, typically "days" for GSOD data. |
... |
Additional arguments. Currently not in use. |
A list
containing start, end, and length of each data gap.
