## Total Daily Precipitation

### Description

This function computes the climdex index PRCPTOT.

### Usage

    climdex.prcptot(ci)

### Arguments

`ci` | Object of type climdexInput.

### Details

This function takes a climdexInput object as input and computes the climdex index PRCPTOT: the annual sum of precipitation in wet days (days where precipitation is at least 1mm).

### Value

A vector containing an annual timeseries of precipitation in wet days.

### 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 sum of precipitation in wet days.
    prcptot <- climdex.prcptot(ci)
