useful for generating semantic row IDs (e.g., for RDF serialization).
Arguments
- x
A dataset created with
dataset_df()
, or a regular data frame.- prefix
A character string used as the prefix for row identifiers. Defaults to
"eg:"
(referring to example.com).- ids
Optional. A character vector of custom IDs to use instead of row names.
Value
A dataset of the same class as x
, with the first column updated to include
unique prefixed identifiers.
