total.precip.op.threshold: Sum of precipitation above a threshold

In climdex.pcic: PCIC Implementation of Climdex Routines

Description

This function returns the sum of values above a threshold for each period (as defined by date.factor).

Usage

total.precip.op.threshold(daily.prec, date.factor, threshold, op)

Arguments

daily.prec	Data to compute index on.
date.factor	Date factor to split by.
threshold	The threshold to compare to.
op	The operator to use to compare data to threshold.

Details

This routine sums up all values which exceed or are below (depending on op) the given threshold.

Value

A timeseries of sums of numbers above the threshold for each period.

Examples

prec.dat <- c(0.1, 3.0, 4.3, 1.9, 1.3, 6.0, 0, 0, 4.0, 1)
phony.date.factor <- factor(rep(1:2, each=5))

## Compute equiv of PRCPTOT
prec.sum <- total.precip.op.threshold(prec.dat, phony.date.factor, 1, ">=")
