climdex.pcic (version 0.1-2)

climdex.txx: climdex.txx

Description

These functions compute the climdex indices TXx, TNx, TXn, and TNn.

Usage

climdex.txx(ci)
climdex.tnx(ci)
climdex.txn(ci)
climdex.tnn(ci)

Arguments

ci

Object of type climdexInput.

Value

• A vector containing the value of the index for each month.

Details

These functions take a climdexInput object as input and compute the climdex indices TXx, TNx, TXn, and TNn. These are:

• TXx:

{Monthly maximum of daily maximum temperature.} TNx:{Monthly maximum of daily minimum temperature.} TXn:{Monthly minimum of daily maximum temperature.} TNn:{Monthly minimum of daily minimum temperature.}

Examples

## Create a climdexInput object from some data already loaded in and
## ready to go.
## tmax.data, tmin.data, and prec.data are vectors of real numbers.
ci <- climdexInput.raw(tmax.data, tmin.data, prec.data,
tmax.dates, tmin.dates, prec.dates, base.range=c(1971, 2000))

## Create a monthly timeseries of maximum daily maximum temperature.
txx <- climdex.txx(ci)

## Create a monthly timeseries of maximum daily minimum temperature.
tnx <- climdex.tnx(ci)

## Create a monthly timeseries of minimum daily maximum temperature.
txn <- climdex.txn(ci)

## Create a monthly timeseries of minimum daily minimum temperature.
tnn <- climdex.tnn(ci)
