guess_type {vroom}

Guess the type of a vector

Description

Guess the type of a vector

Usage

guess_type(
  x,
  na = c("", "NA"),
  locale = default_locale(),
  guess_integer = FALSE
)

Arguments

x

Character vector of values to parse.

na

Character vector of strings to interpret as missing values. Set this option to character() to indicate no missing values.

locale

The locale controls defaults that vary from place to place. The default locale is US-centric (like R), but you can use locale() to create your own locale that controls things like the default time zone, encoding, decimal mark, big mark, and day/month names.

guess_integer

If TRUE, guess integer types for whole numbers, if FALSE guess numeric type for all numbers.

Examples

 # Logical vectors
 guess_type(c("FALSE", "TRUE", "F", "T"))
 # Integers and doubles
 guess_type(c("1","2","3"))
 guess_type(c("1.6","2.6","3.4"))
 # Numbers containing grouping mark
 guess_type("1,234,566")
 # ISO 8601 date times
 guess_type(c("2010-10-10"))
 guess_type(c("2010-10-10 01:02:03"))
 guess_type(c("01:02:03 AM"))
