Convert a Vector of Probability-Weighted Moments to a Probability-Weighted Moments Object

Description

This function converts a vector of probability-weighted moments (PWM) to a PWM object of lmomco. The object is an R list. This function is intended to facilitate the use of PWM that the user might have from other sources. The first five PWMs are supported (\beta_0, \beta_1, \beta_2, \beta_3, \beta_4) if as.list=FALSE otherwise the \beta_r are unlimited.

Usage

vec2pwm(vec, as.list=FALSE)

Arguments

vec	A vector of PWM values in (\beta_0, \beta_1, \beta_2, \beta_3, \beta_4) order.
as.list	A logical controlling the returned data structure.

Value

An R list is returned if as.list=TRUE.

BETA0	The first PWM, which is equal to the arithmetic mean.
BETA1	The second PWM.
BETA2	The third PWM.
BETA3	The fourth PWM.
BETA4	The fifth PWM.
source	Source of the PWMs: “vec2pwm”.

Another R list is returned if as.list=FALSE.

betas	The PWMs.
source	Source of the PWMs: “vec2pwm”.
