as.fd: Frequency distribution of a precipitation serie

In lucasvenez/precintcon: Precipitation Intensity, Concentration and Anomaly Analysis

Description

Calculates the frequency distribution of a daily precipitation serie based on interval.

Usage

as.precintcon.fd(object, interval = 1)

Arguments

object	a daily precipitation serie.
interval	the interval in millimeters for calculating the frequency distribution.

Value

A data.frame (precintcon.fd) containing the following variables:

• initial.class is the initial value of the class.

• final.class is the final value of the class.

• midpoint is the middle point of the class.

• n is the absolute freqnecy, i.e., the number of days in each class.

• sum.n is the cumulative frequency, obtained by adding the absolute frequencies of all the classes up to the one under consideration.

• P is the pluviometric total of each class, obtained by multiplying midpoint by n.

• sum.P is the cummulative class's pluviometric total, obtained by adding the pluviometric total of all the classes up to the one under consideration.

• p.sum.n is the cumulative percentage of rainy days.

• p.sum.P is the cumulative percentage of rainfall amounts.
