rvec-package {rvec}

Package 'rvec'

Description

Tools for working with random draws from a distribution, eg draws from a posterior distribution in a Bayesian analysis.

Details

An rvec holds multiple draws, but wherever possible behaves like an ordinary R vector. For instance, if x is an rvec holding 1000 draws from a distribution, then 2 * x returns a new rvec where each draw has been multiplied by 2.

To summarise across draws, use a function starting with draws. For instance, to calculate a credible interval, use draws_ci().
