powerly vs tf
A side-by-side editorial comparison of powerly and tf — release velocity, themes, recent moves, and the top alternatives to consider.
powerly vs tf: at a glance
What is powerly?
A dormant sample-size package woke up in 2025 with parallel backends and a three-release DOI farce.
powerly implements a simulation-based method for choosing sample sizes in psychological network models. It sat untouched from September 2022 until August 2025, then shipped five releases in two days. v1.10.0 is the substantive one: parabar parallel backends with progress tracking, validation restricted to specific sample sizes, and warnings when the user picks argument values the method cannot support.
What is tf?
tf gave functional data a second dimension: curves whose values are vectors.
tf supplies the vector classes underneath the tidyfun stack — tfd for raw functional observations, tfb for basis-represented ones, both built on vctrs so curves sit in a data frame column and behave like any other vector. Until July that codomain was scalar. The 0.5.0 release adds tfd_mv and tfb_mv, classes for functions whose values are vectors in R^d, and rebuilds the analysis verbs to match.

◆ Current state
powerly implements a simulation-based method for choosing sample sizes in psychological network models. It sat untouched from September 2022 until August 2025, then shipped five releases in two days. v1.10.0 is the substantive one: parabar parallel backends with progress tracking, validation restricted to specific sample sizes, and warnings when the user picks argument values the method cannot support.
◆ Where it's heading
The reawakening tracks the underlying manuscript reaching publication — v1.9.0 is largely citation, DOI, and website work around a published paper, with CI and documentation debt cleared at the same time. Feature work resumed only after that housekeeping, and it points at usability rather than method: better feedback, better progress reporting, the ability to validate one sample size instead of a whole grid. Three of the five 2025 releases exist only to fix a DOI in the package documentation, one of them undoing the previous one.
◆ Prediction
With the paper published and the parallel-backend request from issue #8 finally closed, further releases most likely continue the usability line — more guardrails on argument choice — rather than extending the statistical method itself.

0.0INFRA · APIS
tf gave functional data a second dimension: curves whose values are vectors.
◆ Current state
tf supplies the vector classes underneath the tidyfun stack — tfd for raw functional observations, tfb for basis-represented ones, both built on vctrs so curves sit in a data frame column and behave like any other vector. Until July that codomain was scalar. The 0.5.0 release adds tfd_mv and tfb_mv, classes for functions whose values are vectors in R^d, and rebuilds the analysis verbs to match.
◆ Where it's heading
The package is widening what a functional observation can be, then porting the toolkit onto it. Registration arrived first in 0.4.0 for univariate curves and immediately gained an srvf_mv method for aligning components jointly, and tfb_mfpc() ports principal component analysis to the multivariate case with a single set of scores shared across components. Alongside that runs steady dependency shedding — mvtnorm and pracma both replaced by inlined samplers that reproduce prior draws bit-for-bit, glue dropped for cli in the previous release — and an unusually long tail of NA-handling and edge-case fixes, several caught in pre-release review of the new classes.
◆ Prediction
The new classes ship with FPCA, registration and shape alignment but the release notes describe tidyfun::tf_unnest() as the consumer of one new export, so the visible next step is the rest of the tidyfun stack catching up to vector-valued columns. Expect follow-up patches on the vctrs casting paths, which is where most of this release's late fixes clustered.
