parse_guess {readr} | R Documentation |
parse_guess()
returns the parser vector; guess_parser()
returns the name of the parser. These functions use a number of heuristics
to determine which type of vector is "best". Generally they try to err of
the side of safety, as it's straightforward to override the parsing choice
if needed.
parse_guess(x, na = c("", "NA"), locale = default_locale()) col_guess() guess_parser(x, locale = default_locale())
x |
Character vector of values to parse. |
na |
Character vector of strings to use for missing values. Set this
option to |
locale |
The locale controls defaults that vary from place to place.
The default locale is US-centric (like R), but you can use
