Provides a built-in data frame showing the list of allowed Opal valueType values and their corresponding R data types. This data frame is mainly used for internal processes and programming.
valueType_listdata.frameA data frame with 12 rows and 7 columns:
data type as described in Opal
data type provided by base::typeof(x)
data class provided by attributes(x)
data class provided by base::class(x) explicit class
function to transpose object according base::do.call function
ensemble data type as described in Opal
ensemble data type which valueType belongs
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.
