dataSDA vs IsoriX: at a glance
What is dataSDA?
dataSDA grew from a dataset collection into a symbolic-data conversion toolkit.
The package now carries 105 documented datasets in interval, histogram, modal, and mixed symbolic formats, drawn from other R packages, the Billard and Diday textbooks, and public sources such as the Portuguese air quality network. Alongside the data it has accumulated conversion functions between the MM, RSDA, iGAP, SODAS, and ARRAY representations, CSV read and write support, and a keyword search over the catalogue.
What is IsoriX?
An isotope geolocation package still recovering from the r-spatial retirement
IsoriX builds isoscapes and assigns organisms to geographic origin from stable isotope data. Its recent history is defined by the October 2023 retirement of the old R spatial stack: version 0.9.1 recoded substantial parts of the package to drop raster and sp, 0.9.2 restored capabilities that migration had broken - saving and reloading IsoriX objects, and plotting ocean masks containing holes - and documented the new plotting calls that replace the old sp.polygons and sp.points idioms. Since then 0.9.3 revised the bundled bat calibration datasets and 0.9.4 moved the documentation off bookdown.org.

dataSDA grew from a dataset collection into a symbolic-data conversion toolkit.
◆ Current state
The package now carries 105 documented datasets in interval, histogram, modal, and mixed symbolic formats, drawn from other R packages, the Billard and Diday textbooks, and public sources such as the Portuguese air quality network. Alongside the data it has accumulated conversion functions between the MM, RSDA, iGAP, SODAS, and ARRAY representations, CSV read and write support, and a keyword search over the catalogue.
◆ Where it's heading
The arc across this window runs from cataloguing to tooling. Early releases added datasets and then spent two consecutive releases fixing format documentation across all 105 of them. Later releases shift to functions: format converters, symbolic CSV I/O, and most recently a diagnostic that flags zero-width intervals before they reach tools that divide by interval width. That last addition is the clearest signal of intent — the package is starting to guard the analyses downstream of it, not just supply inputs.
◆ Prediction
Expect further validation helpers in the mould of the zero-width check, since interval data has several degenerate shapes that break downstream methods silently.

An isotope geolocation package still recovering from the r-spatial retirement
◆ Current state
IsoriX builds isoscapes and assigns organisms to geographic origin from stable isotope data. Its recent history is defined by the October 2023 retirement of the old R spatial stack: version 0.9.1 recoded substantial parts of the package to drop raster and sp, 0.9.2 restored capabilities that migration had broken - saving and reloading IsoriX objects, and plotting ocean masks containing holes - and documented the new plotting calls that replace the old sp.polygons and sp.points idioms. Since then 0.9.3 revised the bundled bat calibration datasets and 0.9.4 moved the documentation off bookdown.org.
◆ Where it's heading
Two years of the visible history have gone on infrastructure the science did not ask for. The 0.9.1 notes are unusually candid, warning users that the surrounding package landscape was still in flux and that incompatibility bugs were likely to keep surfacing, which 0.9.2 then confirmed. Only in 0.9.3 does domain work reappear: the bat fur isotope values in the calibration and assignment datasets were corrected to align with current keratin reference material normalisation, so results computed against the old datasets are not comparable with new ones.
◆ Prediction
With the spatial migration settled and the documentation rehomed, the next release is more likely to return to isoscape functionality than to infrastructure, though the entries do not name a specific feature.
