Arguments

• field_name: character. Name of the fields.
• field_label: character. Labels from meta data.
• field_annotation: character. Annotations from meta_data.

unitsFieldAnnotation returns a character vector.

Details

Functions passed into the assignment argument list of exportRecordsTyped() construct attributes on a column. They are expected to have a signature of function(field_name, field_label, field_annotation) and return the attribute to assign or NA. They must be vectorized.

Useful utilities are provided in stringCleanup()

stripHTMLandUnicode strips both HTML and UNICODE from the field_label.

unitsFieldAnnotation pulls a units string from the field_annotation. An example of the form searched for is units=\{"meters"\}

Examples

## Not run:

stripHTMLandUnicode("field_name", "<b>Field label</b>", "field annotation")

unitsFieldAnnotation("field", "label", "units={\"meters\"}")
