Parses text to a flat parse table and subsequently changes its
representation into a nested parse table with nest_parse_data().
Usage
compute_parse_data_nested(
text,
transformers = tidyverse_style(),
more_specs = NULL
)Arguments
- text
The text to parse.
- transformers
Passed to
cache_make_key()to generate a key.- more_specs
Passed to
cache_make_key()to generate a key.
Value
A nested parse table. See tokenize() for details on the columns
of the parse table.
