compositional.mle
An MLE package rebuilt around composable solvers, then renamed to match.
A side-by-side editorial comparison of libr and reporter — release velocity, themes, recent moves, and the top alternatives to consider.
The SAS datastep clone for R just got roughly nineteen times faster.
libr gives R users SAS-style data libraries and a datastep() construct, sitting alongside logr, reporter and procs in the r-sassy suite for analysts moving clinical workflows off SAS. Most of its release history is narrow bug-fixing in the libname() readers, particularly the sas7bdat engine. The exception dominates the window: a single 2026 release that rewrote datastep() performance and cut the installed package to a quarter of its former size.
A clinical-report generator steadily trading automatic layout for user control.
reporter produces paginated statistical reports in RTF, DOCX, PDF, HTML and text from R, aimed at the regulated clinical output that SAS PROC REPORT has traditionally produced. It is the most actively developed component of the r-sassy suite, shipping several releases a year, each a batch of layout capabilities plus pagination fixes. The dominant engineering problem across every release is page breaking, especially in DOCX.

The exception dominates the window: a single 2026 release that rewrote datastep() performance and cut the installed package to a quarter of its former size.
Two threads run through these entries — steady correctness work on SAS file import, and a much less frequent but far more consequential push on making datastep() viable at real data volumes. The recent fix to empty-variable typing suggests the sas7bdat reader is still where edge cases surface. Having addressed both speed and package size in one release, the obvious remaining pressure is correctness and coverage of SAS semantics rather than throughput.
Expect the next releases to continue narrowing sas7bdat import edge cases, with any further datastep() work aimed at supporting more SAS syntax rather than at speed.
reporter produces paginated statistical reports in RTF, DOCX, PDF, HTML and text from R, aimed at the regulated clinical output that SAS PROC REPORT has traditionally produced. It is the most actively developed component of the r-sassy suite, shipping several releases a year, each a batch of layout capabilities plus pagination fixes. The dominant engineering problem across every release is page breaking, especially in DOCX.
The direction is consistently toward exposing control over behaviour that was previously automatic: line breaks, page wrapping, page counts, title blocks and page breaks have all moved from fixed policy to user-settable options. Alongside that, the page header and footer have grown from a fixed structure into a layout region with column widths, centre columns and images. Pagination correctness remains the recurring cost of that flexibility, appearing in nearly every release.
Expect further options carving out exceptions to automatic layout, and continued DOCX pagination fixes, which are the most frequently revisited area in this history.

Latest ship moves from both products, interleaved chronologically. ⚡ = editorial spark.
Both compete on the same themes — sas-migration, r-package, clinical-reporting — within Analytics. libr and reporter are shipping at a similar cadence (velocity 2.5 vs 2.5, both within Sparkpulse's "active" band). See the at-a-glance table above for a side-by-side breakdown of velocity, recent sparks, and editorial themes.
Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. libr and reporter are shipping at a similar cadence (velocity 2.5 vs 2.5, both within Sparkpulse's "active" band).
