lavaanExtra vs piecenikr: at a glance
What is lavaanExtra?
SEM reporting helpers converging on APA output, one CRAN resubmission at a time.
lavaanExtra provides shorthand syntax and formatted output around lavaan structural equation models - write_lavaan() to build model strings, and nice_* functions for fit tables, plots, and modification indices. Three of the six visible releases exist only to satisfy CRAN resubmission: a unicode problem, a dependency version check, tests running without suggested packages. The substance sits in 0.1.5, 0.1.8, and 0.1.9.
What is piecenikr?
Drops the vendor name for the icehouse standard, and adds a notation parser.
piecenikr draws icehouse-style game pieces for R graphics. The 0.2.1 release deprecates its two Looney-branded entry points in favour of generic icehouse_* names and adds four setup functions for common piece configurations. It also ships icehouse_parser(), which plugs the package into ppn::read_ppn() for portable game notation.

◆ Current state
lavaanExtra provides shorthand syntax and formatted output around lavaan structural equation models - write_lavaan() to build model strings, and nice_* functions for fit tables, plots, and modification indices. Three of the six visible releases exist only to satisfy CRAN resubmission: a unicode problem, a dependency version check, tests running without suggested packages. The substance sits in 0.1.5, 0.1.8, and 0.1.9.
◆ Where it's heading
The package generalises its own vocabulary as it goes: lavaan_ind() became lavaan_defined() once it turned out to extract any user-defined parameter, and lavaan_cov() was split so lavaan_cor() covers actual correlations. Methodological positions are taken alongside the API - dropping the estimate argument from lavaan_reg() to force reporting both standardized and unstandardized values, and updating the RMSEA benchmark to Schreiber (2017). Rémi Thériault maintains it next to rempsyc, which formats output to match. Note that 0.1.5 restates the whole 0.1.4.x development series in one body.
◆ Prediction
The pattern points to another nice_* helper aimed at a reporting step that currently needs hand formatting, arriving with the usual CRAN resubmission behind it.

Drops the vendor name for the icehouse standard, and adds a notation parser.
◆ Current state
piecenikr draws icehouse-style game pieces for R graphics. The 0.2.1 release deprecates its two Looney-branded entry points in favour of generic icehouse_* names and adds four setup functions for common piece configurations. It also ships icehouse_parser(), which plugs the package into ppn::read_ppn() for portable game notation.
◆ Where it's heading
The arc runs from a single-vendor drawing helper toward a general renderer for the icehouse piece standard. The two preview releases from 2020 were cosmetic - a colour tweak and the original function set - so almost the whole of the package's current shape arrived in one 2025 release. Naming, colour palette, and the games catalogue all moved together, which reads as a deliberate reset rather than accumulation.
◆ Prediction
With the parser hook in place, the next visible step is more piece setups registered through icehouse_setup_by_name() and icehouse_games(); nothing in these entries points beyond that catalogue.
