R Documentation

Function to read in eiMD parameter chains saved to disk

Description

In ei.MD.bayes, users have the option to save parameter chains for the unit-level betas to disk rather than returning them to the workspace. This function reconstructs the parameter chains by reading them back into R and producing either an array or an mcmc object.

Usage

read.betas(rows, columns, units, dir = NULL, ret.mcmc = TRUE)

Arguments

`rows`	a character vector of the row marginals to be read back in
`columns`	a character vector of the column marginals to be read back in
`units`	a character of numeric vector with the units to be read back in
`dir`	an optional character string identifying the directory in which parameter chains are stored (defaults to `getwd`)
`ret.mcmc`	a logical value specifying whether to return the parameters as an `mcmc` object (defaults to `TRUE`)

Value

If ret.mcmc = TRUE, an mcmc object with row names corresponding to the parameter chains. If ret.mcmc = FALSE, an array with dimensions named according to the selected rows, columns, and units.
