In ECA-D/climind: ECAD Implementation of Climdex Routines

Lengths of strings of TRUE (1 & 0) values Computes which days are above or below the baseline threshold.

Description

This function computes which days are above or below baseline thresholds. It is used to implement the compound indices. It is based on the "percent.days.op.threshold"

Usage

days.op.threshold(temp, dates, jdays, date.factor, threshold.outside.base,
  base.thresholds, base.range, op = "<")

Arguments

temp	Sequence of temperature values.
dates	Sequence of associated dates.
jdays	Sequence of associated days of year.
date.factor	Factor to aggregate data using.
threshold.outside.base	Sequence of thresholds to be used for data outside the base period.
base.thresholds	Data structure containing sets of thresholds to be used inside the base period; see climdexInput-class.
base.range	Date range (type PCICt) of the baseline period.
op	Comparison operator to use.
max.missing.days	Maximum number of NA values per time period.

Value

A vector consisting of the mean fraction of days above or below the supplied set of thresholds.

Note

If date.factor is omitted, daily series will be returned.
