Description

A table of dosage texts with gold standard interpretation, used for testing the algorithm.

Usage

data(testset)

Format

textid: numeric; text identifier
order: numeric; order of dose line (a single dosage text can generate more than one dose line)
text: character; the dosage text
qty: numeric; quantity per dose

Examples

# Import the testset table
data("testset")

# Analyse the testset
results <- testdoseconvert(goldstandard = testset)

# Check there are no incorrect results
if (any(results$outcome == 'actual')){
    print(results[outcome == 'actual' | outcome == 'intended'])
    stop('\nError in analysis of test set.\n')
}
