What is fitVARMxID?

A VAR-model fitting package acquiring the standard R methods it launched without

fitVARMxID fits vector autoregressive models via OpenMx identification, and is one of several packages maintained by the jeksterslab account. Its recent releases are small and additive: confint() and plot() methods, a save function, and before that a documentation pass. The feed also carries automated build commits that are pure CI artifacts.

What is sd2r?

Local Stable Diffusion inference lands in R, shipped as Rcpp bindings over stable-diffusion.cpp

sd2r is a young project wrapping stable-diffusion.cpp for R via Rcpp. The 0.1.0 release established the package structure and the core call surface — sd_ctx(), sd_txt2img(), sd_save_image() — with Vulkan GPU support behind a configure flag and a worked SD 1.5 example at 512x512. The two releases since are not code but asset bundles: precompiled tokenizer vocabularies and BPE merge tables shipped as header files, growing from four tokenizers to twelve.

A VAR-model fitting package acquiring the standard R methods it launched without

◆ Current state

fitVARMxID fits vector autoregressive models via OpenMx identification, and is one of several packages maintained by the jeksterslab account. Its recent releases are small and additive: confint() and plot() methods, a save function, and before that a documentation pass. The feed also carries automated build commits that are pure CI artifacts.

◆ Where it's heading

This is a package settling into R conventions rather than growing capability. Adding confint() and plot() is the standard-methods work most modeling packages do once the estimation core is stable — it signals the author considers the fitting side done. Cadence is roughly quarterly and the changes get smaller each time.

◆ Prediction

Further method coverage — summary(), predict(), or coef() — is the likely next step, since confint() and plot() are usually the first two of that set rather than the last.

Local Stable Diffusion inference lands in R, shipped as Rcpp bindings over stable-diffusion.cpp

◆ Current state

sd2r is a young project wrapping stable-diffusion.cpp for R via Rcpp. The 0.1.0 release established the package structure and the core call surface — sd_ctx(), sd_txt2img(), sd_save_image() — with Vulkan GPU support behind a configure flag and a worked SD 1.5 example at 512x512. The two releases since are not code but asset bundles: precompiled tokenizer vocabularies and BPE merge tables shipped as header files, growing from four tokenizers to twelve.

◆ Where it's heading

The asset releases are the more revealing half of this history. The first bundle covered CLIP, Mistral, Qwen and UMT5 — enough for SD 1.x through Flux. The second adds T5, Gemma, Gemma2 and GPT-OSS merges and splits UMT5 out as the Wan video encoder, so the tokenizer surface now reaches well beyond the image models the package currently exposes. Vocabulary support is being staged ahead of the inference paths that would use it.

◆ Prediction

Given that tokenizers for Flux, SD3 and the Wan video encoder are already bundled while the documented API stops at txt2img, the next step is most likely exposing those model families through the R interface.
