anyflights vs semmcci: at a glance
What is anyflights?
A nycflights13 generator whose recent work is all about the data being right.
anyflights builds nycflights13-style datasets for any US airport and year, downloading flight, weather, airline, airport, and plane tables and optionally packaging them. The four visible releases span 2022 to 2025 and are dominated by keeping those downloads working. The most recent fixes a timezone leak and gaps in hourly weather data.
What is semmcci?
Monte Carlo confidence intervals for SEM, now mostly reacting to upstream deprecations
semmcci generates Monte Carlo confidence intervals for structural equation model parameters, working alongside lavaan. Its four-year release history is a run of patch versions from the jeksterslab account, each adding a function or adjusting method detail. The recent ones are quieter still: the latest addresses a lavaan::getCov() deprecation in tests, and the one before it is described only as minor method edits.

A nycflights13 generator whose recent work is all about the data being right.
◆ Current state
anyflights builds nycflights13-style datasets for any US airport and year, downloading flight, weather, airline, airport, and plane tables and optionally packaging them. The four visible releases span 2022 to 2025 and are dominated by keeping those downloads working. The most recent fixes a timezone leak and gaps in hourly weather data.
◆ Where it's heading
The function surface has been stable since 0.3; everything since concerns the fragility of the upstream sources. Broken URLs for airline data, download failures needing a session-timeout hint, planes data that stopped resolving, and weather values recorded only once an hour have each taken a release. Contributions come from teaching-adjacent users, which fits a package whose main use is generating course datasets.
◆ Prediction
Expect the next release to follow another upstream data-source change rather than to add a table or an argument.

Monte Carlo confidence intervals for SEM, now mostly reacting to upstream deprecations
◆ Current state
semmcci generates Monte Carlo confidence intervals for structural equation model parameters, working alongside lavaan. Its four-year release history is a run of patch versions from the jeksterslab account, each adding a function or adjusting method detail. The recent ones are quieter still: the latest addresses a lavaan::getCov() deprecation in tests, and the one before it is described only as minor method edits.
◆ Where it's heading
The functional build-out finished some time ago. MCGeneric() in 1.1.3 and Func()/MCFunc() in 1.1.4 opened the package to user-defined functions of parameters, which is the natural end point for a Monte Carlo interval tool — once arbitrary functions are supported, there is little left to add. Since then releases have tracked lavaan's changes rather than semmcci's own direction, and the gap between them has stretched from months to over a year.
◆ Prediction
Expect the next release to be triggered by another lavaan deprecation rather than by new capability.
