precintcon (version 2.3.0)

as.fd: Frequency distribution of a precipitation serie

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.
