cIRT vs manymome
A side-by-side editorial comparison of cIRT and manymome — release velocity, themes, recent moves, and the top alternatives to consider.
Shared themes:r-package
cIRT vs manymome: at a glance
What is cIRT?
A choice-based IRT model published once in 2019 and kept compiling ever since
cIRT implements Choice Item Response Theory, jointly modelling which item a respondent picks and how they perform on it — the setting where subjects choose between a harder and an easier question and the choice itself carries information. It comes out of the TMSA Lab, is built on Rcpp and RcppArmadillo, and has had one substantive release since reaching CRAN. Everything after early 2019 is build-system and toolchain upkeep.
What is manymome?
Steady quarterly releases behind a feed that shows almost none of what changed.
manymome computes indirect and moderated effects for path-analysis and SEM models using bootstrap and Monte Carlo intervals. The four most recent CRAN releases (0.3.2 through 0.3.6) publish as bare pointers to the package's own NEWS page, so the feed carries no changelog text for any of them. Where content is visible, at 0.3.1 and 0.2.9, the work is fitting-engine breadth and speed rather than new methodology.

◆ Current state
cIRT implements Choice Item Response Theory, jointly modelling which item a respondent picks and how they perform on it — the setting where subjects choose between a harder and an easier question and the choice itself carries information. It comes out of the TMSA Lab, is built on Rcpp and RcppArmadillo, and has had one substantive release since reaching CRAN. Everything after early 2019 is build-system and toolchain upkeep.
◆ Where it's heading
The package's whole functional history fits in a two-day window in January 2019, when the CRAN release and its immediate follow-ups were tagged in one batch, followed a day later by a release enabling C++11 and OpenMP and fixing the choice generation procedure. Since then the releases track other people's deprecations: Armadillo dropping conversions, RcppArmadillo requiring a different Makevars, R raising its floor. The 2025 release is entirely of that kind, down to swapping the README to Quarto.
◆ Prediction
The dependency floors were just raised to current Rcpp and RcppArmadillo, so the next release is most likely the one after Armadillo deprecates something else.

◆ Current state
manymome computes indirect and moderated effects for path-analysis and SEM models using bootstrap and Monte Carlo intervals.

Where content is visible, at 0.3.1 and 0.2.9, the work is fitting-engine breadth and speed rather than new methodology.
◆ Where it's heading
The legible arc runs toward turning the q_* quick-mediation wrappers into a complete workflow: lavaan::sem fitting with full information maximum likelihood for missing data, a plot method, and user-specified mediation models, alongside repeated optimization of do_boot() and do_mc(). Cadence is roughly quarterly and has held for two years. What the last four versions actually contain cannot be read from this feed.
◆ Prediction
Expect continued quarterly CRAN releases extending the q_* family; beyond that the entries shown do not support a confident call on direction.
