clean_trn: Clean TRN

In maia-sh/ctregistries: Data Package and R Functions for Clinical Trial Registries and other MEDLINE Databanks

Clean TRN

Description

Current limitations: - Single TRN - Only "ANZCTR", "ClinicalTrials.gov", "DRKS", "ISRCTN", "JapicCTI", "EudraCT", "NTR", "PACTR"

Usage

clean_trn(trn, registry = NULL, quiet = FALSE)

Arguments

trn	Character. A single (messy) TRN. Note: Function tested on single TRN input only, so could perform unexpectedly if run on text with other pattern matches or multiple TRNs.
registry	Character. Registry of TRN. Default to NULL and detected to TRN. Note: Currently, always set registry to NULL because would need further input validation.
quiet	Logical. Whether to inform user if TRN changed (and only when TRN changed). Defaults to TRUE.

Value

Cleaned TRN. If error (e.g., if no trn input or registry not in cleaning list), aborts (could change to inform and return NA). If input trn already clean, return is same as input. If TRN is NA, return NA.

Examples

## Not run: 
# Error due to invalid TRN or registry not in
clean_trn("nl)277")
clean_trn("IRCT2016080318745N10")

## End(Not run)
# Already clean so won't inform user
clean_trn("NCT01208194")
# Cleaned so will inform user unless quiet == TRUE
clean_trn("nCt01208194")
clean_trn("nCt01208194", quiet = TRUE)
