Partitions a named list of column tags into chemical, numeric, and metadata categories. This is the single source of truth for tag type membership.
Arguments
Named list where names are column names and values are tag types (e.g., list(col1 = "Name", col2 = "Result"))
Value
Named list with four elements:
- chemical_tags
Named list of chemical-related tags (Name, CASRN, Other)
- numeric_tags
Named list of numeric/measurement tags (Result, Numeric, Unit, Qualifier, ReportingLimit, Uncertainty, UncertaintyCoverage, Duration, DurationUnit)
- metadata_tags
Named list of study metadata tags (Species, ExposureRoute)
- study_type_tags
Named list of study/contextual tags (StudyDate)
Details
Tag type membership per design decisions:
D-06: Chemical types = Name, CASRN, Other
D-07: Numeric types = Result, Numeric, Unit, Qualifier, ReportingLimit, Uncertainty, UncertaintyCoverage, Duration, DurationUnit
D-08: Metadata types = Species, ExposureRoute
Examples
tags <- list(col1 = "Name", col2 = "Result", col3 = "Species")
result <- classify_tags(tags)
result$chemical_tags # list(col1 = "Name")
#> $col1
#> [1] "Name"
#>
result$numeric_tags # list(col2 = "Result")
#> $col2
#> [1] "Result"
#>
result$metadata_tags # list(col3 = "Species")
#> $col3
#> [1] "Species"
#>
