* Fix custom reference_data support in as.sir() (#239) - custom guideline names now correctly classify values as R: CLSI convention (>= breakpoint_R for MIC, <= for disk) applies only when guideline contains "CLSI"; all other guidelines including custom ones use the EUCAST convention (> breakpoint_R for MIC, < for disk) - guideline argument is now optional when reference_data is manually set: if omitted or if its value does not match any row in the custom data, all rows in reference_data are used; if set to a value present in the data, only matching rows are filtered — useful for multi-guideline custom tables - host = NA in custom reference_data now acts as a host-agnostic fallback when no host-specific breakpoint row exists for the current animal species - updated reference_data argument documentation to explain these conventions https://claude.ai/code/session_01Q8KtFFGG9qrjAgLJBbxG2U * Refactor R-classification logic using custom_breakpoints_set flag Introduce custom_breakpoints_set <- !identical(reference_data, AMR::clinical_breakpoints) at the top of as_sir_method() and replace all identical() calls inside that function with this variable. In the case_when_AMR interpretation blocks (MIC and disk), the R-classification now has three explicit arms: - !custom_breakpoints_set & EUCAST guideline -> open interval (> / <) - !custom_breakpoints_set & CLSI guideline -> closed interval (>= / <=) - custom_breakpoints_set -> open interval (> / <), always, regardless of the guideline name in the custom data (e.g. "CLSI_custom" must not accidentally trigger CLSI convention) https://claude.ai/code/session_01Q8KtFFGG9qrjAgLJBbxG2U * Fix unit tests for custom reference_data (#239) - Do not override my_bp$mo / my_bp$ab in tests: assigning plain character strips the <mo>/<ab> class, which check_reference_data() rejects. Use the mo/ab values already present in the source row instead. - Use NA_character_ instead of NA for my_bp$host so the host column keeps its character class. - Pass breakpoint_type = "animal" explicitly in the host-fallback test since the custom reference_data only contains animal-type breakpoints. https://claude.ai/code/session_01Q8KtFFGG9qrjAgLJBbxG2U * Add coerce_reference_data_columns() for lenient reference_data validation check_reference_data() now returns the (possibly coerced) reference_data and the call site captures the result so downstream code sees the fixed columns. A new coerce_reference_data_columns() helper is called before the strict class check inside check_reference_data(). It coerces columns to the expected types: - mo -> as.mo() if not already <mo> class - ab -> as.ab() if not already <ab> class - character columns -> as.character() (e.g. host = NA becomes NA_character_) - numeric columns -> as.double() - logical columns -> as.logical() This allows users to build a custom reference_data from a plain data.frame without having to pre-apply as.mo()/as.ab() or worry about NA column types. Updated the reference_data roxygen argument to document the auto-coercion and restored the tests to the simpler form that uses plain character assignments, relying on the new coercion instead of workarounds. https://claude.ai/code/session_01Q8KtFFGG9qrjAgLJBbxG2U --------- Co-authored-by: Claude <noreply@anthropic.com>
The AMR Package for R
Please visit our comprehensive package website https://amr-for-r.org to read more about this package, including many examples and tutorials.
Overview:
- Provides an all-in-one solution for antimicrobial resistance (AMR) data analysis in a One Health approach
- Peer-reviewed, used in over 175 countries, available in 28 languages
- Generates antibiograms - traditional, combined, syndromic, and even WISCA
- Provides the full microbiological taxonomy of ~79 000 distinct species and extensive info of ~620 antimicrobial drugs
- Applies CLSI 2011-2026 and EUCAST 2011-2026 clinical and veterinary breakpoints, and ECOFFs, for MIC and disk zone interpretation
- Corrects for duplicate isolates, calculates and predicts AMR per antimicrobial class
- Integrates with WHONET, ATC, EARS-Net, PubChem, LOINC, SNOMED CT, and NCBI
- 100% free of costs and dependencies, highly suitable for places with limited resources
The AMR package is a peer-reviewed, free and open-source R package
with zero dependencies to simplify the analysis and prediction of
Antimicrobial Resistance (AMR) and to work with microbial and
antimicrobial data and properties, by using evidence-based methods.
Our aim is to provide a standard for clean and reproducible AMR data
analysis, that can therefore empower epidemiological analyses to
continuously enable surveillance and treatment evaluation in any
setting.
The AMR package supports and can read any data format, including
WHONET data. This package works on Windows, macOS and Linux with all
versions of R since R-3.0 (April 2013). It was designed to work in any
setting, including those with very limited resources. It was created
for both routine data analysis and academic research at the Faculty of
Medical Sciences of the University of Groningen
and the University Medical Center Groningen.
