What is ecodive?

ecodive rebuilt itself into a broad diversity-metric library, breaking as it went

ecodive computes alpha and beta diversity metrics for ecological and microbiome count data, including phylogenetic measures like Faith's PD and the UniFrac family. The 2.0.0 rewrite expanded it from a handful of metrics to roughly fourteen alpha and thirty beta measures while flipping the expected input orientation to samples-as-rows. Subsequent releases have been spent settling the normalisation interface that expansion exposed.

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.

ecodive rebuilt itself into a broad diversity-metric library, breaking as it went

◆ Current state

ecodive computes alpha and beta diversity metrics for ecological and microbiome count data, including phylogenetic measures like Faith's PD and the UniFrac family. The 2.0.0 rewrite expanded it from a handful of metrics to roughly fourteen alpha and thirty beta measures while flipping the expected input orientation to samples-as-rows. Subsequent releases have been spent settling the normalisation interface that expansion exposed.

◆ Where it's heading

This is a package that made its breaking changes deliberately and in a cluster. After 2.0.0 reoriented input and removed the weighted parameter, 2.1.0 superseded rescale with norm, and 2.2.6 changed norm's default from percent to none and removed it from some beta functions entirely. That last one matters more than it reads: normalisation defaults silently change the numbers a metric returns, and the direction is toward making the user state their choice rather than inheriting one.

◆ Prediction

With the metric surface broad and the normalisation interface now explicit, expect the next releases to stabilise — documentation and edge-case handling around CLR and rarefaction rather than another interface break.

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.
