The Beta Function (sfunc)

Description

Computes the (complete) Beta function and its base 10 logarithm.

Usage

Cbeta(a, b, log=FALSE)

Arguments

a, b numeric vectors
log if TRUE, returns the base 10 logarithm of the Beta function (default: FALSE)

Details

This is just a front-end to the built-in beta and lbeta functions, provided mainly for consistent naming. Note that the logarithmic version is scaled to base 10 logarithms, according to the UCS conventions.

Value

The Beta function with arguments (a, b), or its base 10 logarithm (if log=TRUE).
