In pharmaverse/metatools: Enable the Use of 'metacore' to Help Create and Check Dataset

Check Control Terminology for a Single Column

Description

This function checks the column in the dataset only contains the control terminology as defined by the metacore specification

Usage

check_ct_col(data, metacore, var, na_acceptable = NULL)

Arguments

data	Data to check
metacore	A metacore object to get the codelist from. If the variable has different codelists for different datasets the metacore object will need to be subsetted using select_dataset from the metacore package.
var	Name of variable to check
na_acceptable	Logical value, set to NULL by default, so the acceptability of missing values is based on if the core for the variable is "Required" in the metacore object. If set to TRUE then will pass check if values are in the control terminology or are missing. If set to FALSEthen NA will not be acceptable.

Value

Given data if column only contains control terms. If not, will error given the values which should not be in the column

Examples

library(metacore)
library(haven)
library(magrittr)
load(metacore_example("pilot_ADaM.rda"))
spec <- metacore %>% select_dataset("ADSL")
data <- read_xpt(metatools_example("adsl.xpt"))
check_ct_col(data, spec, TRT01PN)
check_ct_col(data, spec, "TRT01PN")
