What is units?

units reaches 1.0 by rewriting its parser and accepting the breakage that comes with it.

units attaches physical units to R vectors on top of the udunits2 library, covering arithmetic, conversion and ggplot2 scales. Version 1.0-0 replaced the unit-expression tokenizer so numbers are consistently treated as prefixes, and expressions like ml/min/1.73m^2 now parse the way physiologists write them. Printing follows NIST conventions, and 1.0-1 is a fix pass over memory handling and parser edge cases.

What is vegan?

Community ecology's standard toolkit is retiring the functions a generation of scripts was built on.

vegan is the reference R package for ordination and diversity analysis in community ecology. The 2.7 line redesigned constrained ordination graphics from scratch, made adonis defunct in favor of adonis2, and moved permutation tests for partial RDA and db-RDA onto residualized predictors. The current 2.7-5 release is stabilization — parallel processing on Windows, ggvegan compatibility for tidy scores, and arrow label placement.

units vs vegan: editorial side-by-side

units reaches 1.0 by rewriting its parser and accepting the breakage that comes with it.

◆ Current state

units attaches physical units to R vectors on top of the udunits2 library, covering arithmetic, conversion and ggplot2 scales. Version 1.0-0 replaced the unit-expression tokenizer so numbers are consistently treated as prefixes, and expressions like ml/min/1.73m^2 now parse the way physiologists write them. Printing follows NIST conventions, and 1.0-1 is a fix pass over memory handling and parser edge cases.

◆ Where it's heading

The long 0.8-x run was accretion — ggplot2 scales absorbed from ggforce, ud_convert(), matrix methods, steady performance work — while known parsing defects stayed in place. The 1.0 release finally traded backwards compatibility for correct parsing, and 1.0-1's pointer-wrapping and exception-propagation work suggests the C++ glue is being hardened behind it. Fixes cluster at the udunits2 boundary, which remains the main source of surprises.

◆ Prediction

Expect continued patch releases against udunits2 quirks and the new tokenizer's fallout rather than new surface area, with the ggplot2 integration and conversion helpers already in place.

Community ecology's standard toolkit is retiring the functions a generation of scripts was built on.

◆ Current state

vegan is the reference R package for ordination and diversity analysis in community ecology. The 2.7 line redesigned constrained ordination graphics from scratch, made adonis defunct in favor of adonis2, and moved permutation tests for partial RDA and db-RDA onto residualized predictors. The current 2.7-5 release is stabilization — parallel processing on Windows, ggvegan compatibility for tidy scores, and arrow label placement.

◆ Where it's heading

Two long deprecation programs are converging. Plotting is being pushed out of the package: lattice functions are deprecated in favor of ggplot2 equivalents now living in ggvegan, a separate CRAN package, while vegan's own base graphics were rebuilt around independently configurable score types and pipe-based construction. Meanwhile the statistical core is being made internally consistent — add1 and drop1 no longer use different internal models, and summary is no longer an accepted route to ordination scores.

◆ Prediction

Expect the remaining lattice functions to go defunct and more plotting responsibility to shift to ggvegan, leaving vegan as the statistical engine with a thin base graphics layer.
