mcmcr 0.7.0.9002

• Internal changes only.

mcmcr 0.7.0.9001

• Same as previous version.

mcmcr 0.7.0.9000

• Switching to development version.

mcmcr 0.7.0 (2026-08-30)

New features

• coef() methods and tidy.mcmcr() gain a directional_information argument. When TRUE the svalue column reports extras::directional_information() in place of extras::svalue() (#71, #84). The default is currently FALSE and will change to TRUE in a future release; calling either function without setting directional_information now signals a deprecation warning so the change can be made explicit.

Breaking changes

• tidy.mcmcr() now defaults to simplify = TRUE, matching the nlist tidy() methods.
• coef(simplify = FALSE), deprecated in 0.4.1, is now defunct (#74).
• The re-exports of term's parameters() and parameters<-(), which are defunct in term, have been removed (#85).
• rhat.mcmcrs(bound = TRUE) now returns a named list of scalars rather than a single scalar; use rhat(x, bound = TRUE)$bound for the previous behavior. The change is signaled with a warning (#74).

Deprecations

The following, soft-deprecated in 0.2.1, now warn on every use (#72):

• terms(); use as_term() instead.
• zero(); use fill_all() instead.
• check_mcmcarray() and check_mcmcr(); use chk_mcmcarray() and chk_mcmcr() instead.
• subset(iterations = ) and subset(parameters = ); use subset(iters = ) and subset(pars = ) instead.
• pars(terms = ); use term::pars_terms(as_term(x)) for terms = TRUE, and pars(x) for terms = FALSE.

Minor improvements and fixes

• extras is now required at version 0.10.0 or later, and nlist at version 0.5.0 or later.

mcmcr 0.6.2 (2025-01-23)

• Depends on R >= 4.0.
• When bound = TRUE rhat() now also returns rhat values for separate analyses.
• When bound = TRUE and as_df = TRUE rhat() now returns a data.frame with the rhat values for the separate and combined analyses.

mcmcr 0.6.1 (2021-09-06)

• Update testing to testthat 3.

mcmcr 0.6.0 (2021-08-05)

• Added fill_na() for mcarray, mcmcarray and mcmcr.
• Fixed as.mcmcarray.mcmc() (and as.mcmcr.mcmc()) so now returns an mcmcarray (and mcmcr) object with no terms.

mcmcr 0.5.0 (2021-02-11)

• Added
  • tidy.mcmcr().
  • simplify = FALSE argument to coef() and tidy() and soft-deprecated if not TRUE.
  • ... optional arguments for fun = median argument to estimates().
• Moved as_nlists.mcmc.list() to nlist package.

mcmcr 0.4.0 (2020-09-27)

• Added as_mcmc_list.mcmr().
• Moved the following to nlist
  • as_nlist.mcmc() and as_nlist.mcmc.list()
  • as_nlists.mcmc()
  • as.term.mcmc() and as.term.mcmc.list()
  • bind_iterations.mcmc() and bind_iterations.mcmc.list()
  • collapse_chains.default() and collapse_chains.mcmc.list()

mcmcr 0.3.0 (2020-07-13)

• Changed

  • npdims.mcmc.list() to return character vector (as opposed to list)
  • collapse_chains.mcmc.list() to return an mcmc.list object with one chain (as opposed to an mcmc object)
  • first argument of estimates() from object to x.
  • scalar_only = FALSE argument of pars() to scalar = NA.
  • estimates() so now checks fun returns scalar numeric.

• Soft-deprecated

  • pvalue() for extras::pvalue().
  • zero() for fill_all().
  • check_mcmcarray() and check_mcmcr() for chk_mcmcarray() and chk_mcmcr().
  • iterations argument with iters in subset().
  • parameters argument with pars in subset().

• Added

  • vld_() and chk_() functions for mcmcarray and mcmcr objects.
  • scalar = NULL argument to pars() and npars().
  • na_rm = NA argument to esr() and rhat().
  • missing as_df = FALSE arg to esr() for mcarray, mcmc and mcmc.list.
  • coercion to and from nlists objects for mcmcr, mcmc.list and mcmc objects.

• Moved

  • handling of terms to term package.
  • generic definitions of nchains(), niters(), collapse_chains() and split_chains() etc to universals package.

mcmcr 0.2.0 (2019-06-27)

• Added check_mcmcr() and check_mcmcarray().
• Fixed by and as_df arguments in converged().
• Added more tests.
• Removed as.mcmc.mcmc.list(), thin.mcmc() and thin.mcmc.list() as now defined by coda.
• No longer export as.mcmc.list.mcarray() as clashes with rjags version.

mcmcr 0.1.0 (2019-04-26)

• Added mcmc_aperm() function to transpose parameter dimensions.
• Added npdims() function to get number of parameter dimensions.
• Added by = TRUE argument to mcmc_map() function.
• Removed tibble package from suggests.
• rhat() now returns minimum of 1.
• Defined subset() and parameters() for mcmcrs object.
• Added bound = FALSE argument to rhat.mcmcrs() and converged.mcmcrs() functions.

mcmcr 0.0.3 (2018-11-24)

• Moved graphics, coef, tibble packages from imports to suggests.
• Replaced internal error() with err::err().

mcmcr 0.0.2 (2018-10-30)

• Allowed NAs in values to calculate pvalues.
• Updated to not use length argument in checkr as deprecated.

mcmcr 0.0.1 (2018-04-13)

• Released to CRAN.
