mcmcr 0.7.0

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.
