What is r2rtf?

The clinical-report table engine learned Chinese, then learned to leave RTF entirely

r2rtf builds the RTF tables, listings and figures that go into clinical study reports, and its recent releases have been about widening who and what it can serve rather than changing how tables are composed. The 1.2.0 release added internationalization — a SimSun font path for Chinese characters plus hyphenation control — and 1.3.0 followed with write_docx() and write_html(), turning the LibreOffice conversion the package had documented into exported functions.

What is sparsevctrs?

Sparse vectors stopped being a storage trick and became something you can do arithmetic on

sparsevctrs supplies sparse vectors that live inside ordinary data frames and tibbles, which is what lets tidymodels carry wide, mostly-zero feature matrices without densifying them. Through 0.2.0 and 0.3.0 the package built out a computation layer on top of that storage — first summary statistics, then scalar and element-wise arithmetic — and everything since has been correctness work at the C level.

The clinical-report table engine learned Chinese, then learned to leave RTF entirely

◆ Current state

r2rtf builds the RTF tables, listings and figures that go into clinical study reports, and its recent releases have been about widening who and what it can serve rather than changing how tables are composed. The 1.2.0 release added internationalization — a SimSun font path for Chinese characters plus hyphenation control — and 1.3.0 followed with write_docx() and write_html(), turning the LibreOffice conversion the package had documented into exported functions.

◆ Where it's heading

Two threads run through the window. One is output reach: RTF remains the composition target, but the artifacts that come out of it now include DOCX and HTML, and page numbering can be made table-relative across multi-page tables. The other is durability under a moving R and font stack — the ANSI/Unicode converter was rebuilt, the LaTeX mapping table generated from code rather than shipped as sysdata, unlist() usage fixed for R 4.5, and graphics-device leaks that produced stray Rplots.pdf closed off.

◆ Prediction

Having exported DOCX and HTML conversion, the likely next step is filling in what those formats lose relative to RTF — pagination and footnote fidelity are the obvious gaps. The i18n path currently covers Chinese only, so additional font families are the other plausible direction.

Sparse vectors stopped being a storage trick and became something you can do arithmetic on

◆ Current state

sparsevctrs supplies sparse vectors that live inside ordinary data frames and tibbles, which is what lets tidymodels carry wide, mostly-zero feature matrices without densifying them. Through 0.2.0 and 0.3.0 the package built out a computation layer on top of that storage — first summary statistics, then scalar and element-wise arithmetic — and everything since has been correctness work at the C level.

◆ Where it's heading

The release pattern splits cleanly at 0.3.0. Before it, new functions arrive in batches; after it, five consecutive releases are bug fixes, and the bugs are the kind that come with hand-written sparse kernels: a stack imbalance when sparse_multiplication() returns all zeros, undefined behaviour in multiplication, type errors in sparse_is_na(), coercion failures on NA input. That is the expected cost of an ALTREP-backed numerical layer, and the fixes are landing steadily.

◆ Prediction

With the arithmetic surface in place and the recent releases all narrow fixes, the next one is more likely another correctness patch than a new function family. The R devel fix in 0.3.5 suggests upcoming R releases are the current source of breakage.

Frequently asked questions

What is the difference between r2rtf and sparsevctrs?

They serve adjacent needs but don't currently overlap on shipped themes. r2rtf and sparsevctrs are shipping at a similar cadence (velocity 0.0 vs 0.0, 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.

Is r2rtf better than sparsevctrs?

Sparkpulse doesn't pick a winner — we score release velocity, not feature parity. r2rtf and sparsevctrs are shipping at a similar cadence (velocity 0.0 vs 0.0, both within Sparkpulse's "active" band).
