pakret vs slendr
A side-by-side editorial comparison of pakret and slendr — release velocity, themes, recent moves, and the top alternatives to consider.
pakret vs slendr: at a glance
What is pakret?
Package citation for R documents, quietly growing to meet Quarto.
pakret inserts citations for R packages into R Markdown and Quarto documents, resolving each package to a BibTeX entry and writing the .bib file that backs it. Version 0.3.1 adds support for Quarto's inline syntax and separator control when citing several packages in one inline chunk, following 0.3.0, which made the package create missing .bib files, preserve capitalisation in reference titles, and treat the version placeholder in citation templates as optional. Cadence is a handful of small releases a year.
What is slendr?
Population-genetic simulation in R, opened up to selection and finally easier to install.
slendr specifies spatial and non-spatial population-genetic models in R and simulates them through SLiM or msprime, returning tree sequences that tskit then analyses. Two threads dominate the current releases: keeping in step with fast-moving backends, with SLiM 5.1, pyslim 1.1.0 and Python 3.13 now required, and reducing the setup burden that its Python dependency imposes. Version 1.5.0 adds ephemeral uv-based virtual environments, so init_env(uv = TRUE) can stand in for creating a permanent environment with setup_env().

Package citation for R documents, quietly growing to meet Quarto.
◆ Current state
pakret inserts citations for R packages into R Markdown and Quarto documents, resolving each package to a BibTeX entry and writing the .bib file that backs it. Version 0.3.1 adds support for Quarto's inline syntax and separator control when citing several packages in one inline chunk, following 0.3.0, which made the package create missing .bib files, preserve capitalisation in reference titles, and treat the version placeholder in citation templates as optional. Cadence is a handful of small releases a year.
◆ Where it's heading
Every release in this window removes a specific friction someone hit while writing a document. Bib files that had to exist beforehand now get created; single-letter package names like R and C stopped being lower-cased in titles; the package works when loaded after conflicted; citing many packages got faster; and version numbers became optional for documents where they are noise. The 0.3.1 Quarto support extends the same idea to the format its users are moving to. Nothing here is architectural, and nothing needs to be.
◆ Prediction
Expect continued alignment with Quarto as more of its syntax surfaces become relevant, and further refinement of how multi-reference packages resolve to a single entry, which the BibTeX type priority work in 0.2.0 started. The entries give no indication of a 1.0.

Population-genetic simulation in R, opened up to selection and finally easier to install.
◆ Current state
slendr specifies spatial and non-spatial population-genetic models in R and simulates them through SLiM or msprime, returning tree sequences that tskit then analyses. Two threads dominate the current releases: keeping in step with fast-moving backends, with SLiM 5.1, pyslim 1.1.0 and Python 3.13 now required, and reducing the setup burden that its Python dependency imposes. Version 1.5.0 adds ephemeral uv-based virtual environments, so init_env(uv = TRUE) can stand in for creating a permanent environment with setup_env().
◆ Where it's heading
Since the 1.0.0 release added non-neutral simulation, the work has shifted from capability to friction. A large share of recent notes concerns Python environment handling, conda activation races on Windows, dependency pruning that made shiny optional, and argument names that misled users, as when gene_flow()'s rate argument turned out to mean total ancestry proportion rather than a rate. That is the profile of a package whose scientific surface is settled and whose remaining problems are the ones users actually hit.
◆ Prediction
Expect the uv-based environment path to move from fallback to default once it has proven itself, given the notes already describe an environment variable for making it so. The deprecated rate argument in gene_flow() is explicitly slated for removal in a future major release, which is the clearest signal here of what a 2.0 would contain.
