climdex.rnnmm: Precipitation Exceeding A Specified Amount Per Day

In climdex.pcic: PCIC Implementation of Climdex Routines

Description

This function computes the climdex index Rnnmm.

Usage

climdex.rnnmm(ci, threshold = 1)

Arguments

ci	Object of type climdexInput.
threshold	The threshold to be used for Rnnmm.

Details

This function takes a climdexInput object as input and computes the climdex index Rnnmm: the annual count of days where daily precipitation is more than nn mm per day.

Value

A vector containing the value of the index for each year.

Examples

library(PCICt)

## Create a climdexInput object from some data already loaded in and
## ready to go.

## Parse the dates into PCICt.
tmax.dates <- as.PCICt(do.call(paste, ec.1018935.tmax[,c("year",
"jday")]), format="%Y %j", cal="gregorian")
tmin.dates <- as.PCICt(do.call(paste, ec.1018935.tmin[,c("year",
"jday")]), format="%Y %j", cal="gregorian")
prec.dates <- as.PCICt(do.call(paste, ec.1018935.prec[,c("year",
"jday")]), format="%Y %j", cal="gregorian")

## Load the data in.
ci <- climdexInput.raw(ec.1018935.tmax$MAX_TEMP,
ec.1018935.tmin$MIN_TEMP, ec.1018935.prec$ONE_DAY_PRECIPITATION,
tmax.dates, tmin.dates, prec.dates, base.range=c(1971, 2000))

## Create an annual timeseries of the R1mm index.
rnnmm <- climdex.rnnmm(ci)
