What is DataSpaceR?

DataSpaceR's 1.0.0 rebuilt its query API and opened up HIV antibody sequence data.

The R client for the CAVD DataSpace reached 1.0.0 in July 2026 after five years of small fixes. The release removed the mAb grid filtering and view methods in favour of filtering an availableMabs object with data.table syntax, applied that pattern to every query method, and added a class for querying DAASH, the Database of Annotated Antibody Sequences for HIV-1. The August patch restored the LANL monoclonal-antibody metadata requests and batched BCR sequence queries.

What is lang?

R help pages translated on demand by whichever LLM you point it at.

lang translates R help documentation at read time using a language model of the user's choosing, rendering the result directly in the RStudio or Positron help pane rather than producing translated files. The two releases since launch have both targeted translation quality rather than reach: 0.1.1 added a context_size argument that summarizes the full help page and injects it into every field's prompt so terminology stays consistent across sections, and rewrote Rd parsing around a structured intermediate representation instead of regex. Version 0.1.2 then made that context conditional, omitting it for inputs of ten words or fewer.

2.5

DataSpaceR's 1.0.0 rebuilt its query API and opened up HIV antibody sequence data.

◆ Current state

The R client for the CAVD DataSpace reached 1.0.0 in July 2026 after five years of small fixes. The release removed the mAb grid filtering and view methods in favour of filtering an availableMabs object with data.table syntax, applied that pattern to every query method, and added a class for querying DAASH, the Database of Annotated Antibody Sequences for HIV-1. The August patch restored the LANL monoclonal-antibody metadata requests and batched BCR sequence queries.

◆ Where it's heading

The package is converging on one query idiom — build a filtered object, then fetch — instead of per-domain grid methods, and each class now accepts multiple studies or antibodies rather than one. The 1.0.1 patch suggests the rewrite dropped functionality that users noticed, and it was put back rather than redesigned.

◆ Prediction

With DAASH access in place and the query surface unified, the next work is most likely more sequence-domain coverage and follow-up fixes to the batched query paths introduced in 1.0.1.

0.0

R help pages translated on demand by whichever LLM you point it at.

◆ Current state

lang translates R help documentation at read time using a language model of the user's choosing, rendering the result directly in the RStudio or Positron help pane rather than producing translated files. The two releases since launch have both targeted translation quality rather than reach: 0.1.1 added a context_size argument that summarizes the full help page and injects it into every field's prompt so terminology stays consistent across sections, and rewrote Rd parsing around a structured intermediate representation instead of regex. Version 0.1.2 then made that context conditional, omitting it for inputs of ten words or fewer.

◆ Where it's heading

The work is converging on the failure modes specific to running documentation translation through a model rather than a translation service. The Rd rewrite through rd_to_list() and list_to_rd() removes a class of formatting corruption that regex manipulation invited. The context-window tuning addresses the opposite problem — a local model handed a context summary longer than the field it is translating paraphrases the context instead. Both fixes are about making small, weaker, locally hosted models behave, which suggests that is the deployment the package expects.

◆ Prediction

Given that both post-launch releases tune prompt construction for local models, expect further per-field prompt heuristics rather than new output targets.
