META: Metadata for the master dictionary, stored in a data.table
In CALIBERcodelists: Generate ICD10, Read and OPCS codelists

Description Format Details See Also

This is a data.table for storing metadata for any codelists being developed using the master dictionary (CALIBER_DICT). It is hidden in the CALIBERcodelists namespace, and values can be set by setMetadata.

A data.table with 12 observations on the following 2 variables.

item: a character vector, key column
value: a character vector, value of the item

The data.table contains the following data (item, value):

Author: User-supplied codelist name (without the _gprd, _hes or _opcs suffix)
category: Category numbers, stored as a pipe separated string
Date: User-supplied date to record for the codelist
description: Category descriptions, stored as a pipe separated string
icd10: Whether the ICD-10 dictionary is in use, TRUE or FALSE as a character string
message: Used to temporarily store the output message of compare
Name: User-supplied codelist name (without the _gprd, _hes or _opcs suffix)
opcs: Whether the OPCS dictionary is in use, TRUE or FALSE as a character string
read: Whether the Read dictionary is in use, TRUE or FALSE as a character string
shortname: Brief category descriptions, stored as a pipe separated string
spreadsheet: (Not relevant for Windows) User-supplied name of spreadsheet program for opening .CSV files, e.g. libreoffice

The META table can only be modified by changing the values of a cell by reference. It is sealed inside the namespace so the number of rows and columns, or the type of data in columns cannot be altered while the package is loaded.

If a codelist is generated from the master dictionary using as.codelist, the metadata for the codelist is drawn from the META table.
