Convert typeof (and class if any) into its corresponding valueType

Source: R/04-catalogue_functions.R

The function converts a given typeof string into its corresponding valueType representation. This function is particularly useful for mapping different data types to their equivalent value types in contexts such as data modeling and data dictionary creation. An optional class parameter allows for more specific conversions when necessary.

typeof_convert_to_valueType(typeof, class = NA_character_)

Arguments

typeof

A string representing the type to be converted. Supported values include "character", "integer", "double", "logical".

class

An optional parameter that specifies a class context. If provided, the function may return a more refined value type based on the class type; if not, the function will return a general equivalent. Supported values include "character", "integer","numeric","logical","Date" and "POSIXct". NULL is the default.

Value

A character vector, named 'valueType'.

Details

The valueType is a declared property of a variable that is required in certain functions to determine handling of the variables. Specifically, valueType refers to the OBiBa data type of a variable. The valueType is specified in a data dictionary in a column 'valueType' and can be associated with variables as attributes. Acceptable valueTypes include 'text', 'integer', 'decimal', 'boolean', datetime', 'date'. The full list of OBiBa valueType possibilities and their correspondence with R data types are available using valueType_list. The valueType can be used to coerce the variable to the corresponding data type.

Examples

{

typeof_convert_to_valueType(typeof = "character")
typeof_convert_to_valueType(typeof = "double")
typeof_convert_to_valueType(typeof = "double", class = "Date")

}
#> valueType 
#>    "date"
