drop_index

Removes square brackets, numbers, and commas that represent
the index of the node element in question. Returns just the node name.

The aim of 'postpack' is to provide the infrastructure for a standardized workflow for 'mcmc.list' objects.
These objects can be used to store output from models fitted with Bayesian inference using
'JAGS', 'WinBUGS', 'OpenBUGS', 'NIMBLE', 'Stan', or even custom MCMC algorithms. Although the 'coda' R package provides
some methods for these objects, it is somewhat limited in easily performing post-processing tasks for
specific nodes. Models are ever increasing in their complexity and the number of tracked nodes, and oftentimes
a user may wish to summarize/diagnose sampling behavior for only a small subset of nodes at a time
for a particular question or figure. Thus, many 'postpack' functions support performing tasks on a
subset of nodes, where the subset is specified with regular expressions. The functions in 'postpack'
streamline the extraction, summarization, and diagnostics of specific monitored nodes after model fitting.
Further, because there is rarely only ever one model under consideration, 'postpack' scales efficiently
to perform the same tasks on output from multiple models simultaneously, facilitating rapid assessment
of model sensitivity to changes in assumptions.
