R/mdro.R:
Qualify setNames() as stats::setNames() in the drug+inhibitor inference
block to satisfy R CMD CHECK's global-function checks.
tests/testthat/test-mdro.R:
mdro() with verbose=FALSE returns an atomic ordered factor, not a
data.frame. Fix three test errors introduced in the previous commit:
- Line 320: result_no_pip$MDRO -> result_no_pip (factor, no $ accessor)
- Line 328: result_tzp_s$MDRO / result_no_pip$MDRO -> direct factor refs
- Line 347: expect_inherits(..., "data.frame") -> c("factor","ordered")
Also fix the comment on line 347 to match the actual return type.
Version: confirmed at 3.0.1.9029 (no further bump; one bump already made
this PR). git describe failed (no tags in dev environment) — fallback
applies. The +1 in CLAUDE.md's formula is correct for tagged repos:
currentcommit + 9001 + 1 = 27 + 9001 + 1 = 9029 ✓

R/sir.R (line 571):
Guard purely numeric strings (e.g. "1", "8") from the Unicode letter
filter. Values matching the broad SIR regex but consisting only of digits
must not be stripped; add `x %unlike% "^[0-9+]$"` predicate.
R/mic.R (lines 220-222):
Preserve the letter 'e' during Unicode-letter removal so that MIC values
in scientific notation (e.g. "1e-3", "2.5e-2") survive the cleaning step.
- Line 220: [\\p{L}] → [^e\\P{L}] (remove all letters except 'e')
- Line 222: [^0-9.><= -]+ → [^0-9e.><= -]+ (allow 'e' in whitelist)
tests/testthat/test-mdro.R:
New tests for the drug+inhibitor inference added in the previous commit
(issue #209):
- TZP=R with no PIP column → PIP inferred R → MDRO class elevated
- TZP=S with no PIP column → proxy col is NA (not S) → class lower
- verbose mode emits "Inferring resistance" message
- AMC=R with no AMX column runs without error (Enterococcus faecium)
https://claude.ai/code/session_01Cp154UtssHg84bw38xiiTG
When a base beta-lactam column (e.g., piperacillin/PIP) is absent but a
corresponding drug+inhibitor combination (e.g., piperacillin/tazobactam/TZP)
is present and resistant, resistance in the base drug is now correctly
inferred. This is clinically sound: resistance in a combination implies the
inhibitor provided no benefit, so the base drug is also resistant.
Susceptibility in a combination is NOT propagated to the base drug (the
inhibitor may be responsible for susceptibility), so only R values are
inferred; missing base drugs remain NA otherwise.
Implementation details:
- Uses AB_BETALACTAMS_WITH_INHIBITOR to identify all beta-lactam+inhibitor
combinations present in the user's data
- Derives base drug AB codes by stripping the "/inhibitor" part from names
- Creates synthetic proxy columns (.sir_proxy_<AB>) in x, set to "R" when
any matching combination is R, otherwise NA
- Proxy columns are added to cols_ab before drug variable assignment,
so all existing guideline logic benefits without any changes
- Multiple combos for the same base drug are OR-ed (any R → R)
- Adds internal ab_without_inhibitor() helper for the name->base mapping
- Verbose mode reports which combinations are used for inference

* fix: restore valid AB codes mangled by generalise_antibiotic_name() (#245)
When as.ab() received a vector containing both valid AB codes (like ETH,
PHN, PHE, STH, THA, MTH, THI1) and an untranslatable value, the fast
path at line 100 was skipped. The slow path then applied
generalise_antibiotic_name(), which rewrites "TH"->"T" and "PH"->"F",
mangling these short AB codes (e.g. ETH->"ET", PHN->"FN") so they could
no longer be found in the lookup table.
Fix: save the pre-generalised values before applying
generalise_antibiotic_name(), then restore any elements that were already
valid AB codes in their original form.

* fix: use toupper() in AB code restoration to handle lowercase input (#245)
Ensures that lowercase user input (e.g. 'eth', 'phn') is matched
case-insensitively against the uppercase AB codes in $ab, and that
the restored value is stored in uppercase to match the lookup table.
https://claude.ai/code/session_01Sujw89qa48NoUmMPDBJLz9
* revert: remove unnecessary toupper() since x is already uppercased
https://claude.ai/code/session_01Sujw89qa48NoUmMPDBJLz9
* Revise versioning and date bump requirements for PRs
Updated versioning instructions for pull requests to include date bump.
