read.betas: 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.
