What is DoseFinding?

New stewardship at openpharma, then two releases adding the methods MCP-Mod was missing

DoseFinding implements MCP-Mod and related dose-response methodology for clinical trial design and analysis. In 2024 it changed hands — Marius Thomas took over as maintainer, Novartis was recorded as copyright holder and funder, and the package moved to the openpharma GitHub organisation with roxygen documentation and a proper NEWS file. The two releases since have added substantive methodology: model averaging for dose-response fitting in 1.3-1, and conditional and predictive power for interim analyses in 1.4-1.

What is lightr?

Reorganised its parsers by vendor, then opened the parser slot to users.

lightr reads spectrometry files from the proprietary formats that instrument vendors ship, and its recent releases have been about the structure of that parser collection rather than adding one more format. Version 2.0.0 renamed every low-level parser from lr_parse_<extension>() to lr_parse_<brand>_<extension>(), a breaking change made specifically so two vendors can share a file extension without colliding, and restored binary parsing for Avantes AvaSoft 8.4 using vendor-supplied format documentation. Version 2.1.0 follows through by exposing a parser argument on the high-level functions.

New stewardship at openpharma, then two releases adding the methods MCP-Mod was missing

◆ Current state

DoseFinding implements MCP-Mod and related dose-response methodology for clinical trial design and analysis. In 2024 it changed hands — Marius Thomas took over as maintainer, Novartis was recorded as copyright holder and funder, and the package moved to the openpharma GitHub organisation with roxygen documentation and a proper NEWS file. The two releases since have added substantive methodology: model averaging for dose-response fitting in 1.3-1, and conditional and predictive power for interim analyses in 1.4-1.

◆ Where it's heading

The pattern before the handover was maintenance — R-devel compliance, a bug fix, a link. After it, each release carries a named methodological addition with an acknowledged contributor, plus documentation to match: a longitudinal analysis vignette shipped alongside the interim power work. Housekeeping continues underneath, mostly clearing deprecated ggplot2 interfaces, aes_string in one release and qplot in the next.

◆ Prediction

Given the last two releases each added one method with a supporting vignette, expect the next to follow the same shape. Both additions so far extend the package beyond fixed dose-response fitting, so adaptive and interim methodology is the more likely direction.

Reorganised its parsers by vendor, then opened the parser slot to users.

◆ Current state

lightr reads spectrometry files from the proprietary formats that instrument vendors ship, and its recent releases have been about the structure of that parser collection rather than adding one more format. Version 2.0.0 renamed every low-level parser from lr_parse_<extension>() to lr_parse_<brand>_<extension>(), a breaking change made specifically so two vendors can share a file extension without colliding, and restored binary parsing for Avantes AvaSoft 8.4 using vendor-supplied format documentation. Version 2.1.0 follows through by exposing a parser argument on the high-level functions.

◆ Where it's heading

The package is moving from a fixed set of formats it knows about to a dispatch system users can extend. The brand-qualified naming and the parser argument are two halves of the same design: name parsers unambiguously, then let callers select or supply one. Alongside that runs steady attention to metadata fidelity — measurement timestamps, checksum verification against tampering, and timezone handling that survived upstream tzdata removing legacy codes.

◆ Prediction

Expect additional vendor parsers to arrive under the new brand-qualified scheme, and the custom-parser path to absorb formats the maintainers do not want to support directly. The entries do not name specific instruments planned next.
