Guess the type of a vector

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"))
#> <collector_logical>
 # Integers and doubles
 guess_type(c("1","2","3"))
#> <collector_double>
 guess_type(c("1.6","2.6","3.4"))
#> <collector_double>
 # Numbers containing grouping mark
 guess_type("1,234,566")
#> <collector_number>
 # ISO 8601 date times
 guess_type(c("2010-10-10"))
#> <collector_date>
 guess_type(c("2010-10-10 01:02:03"))
#> <collector_datetime>
 guess_type(c("01:02:03 AM"))
#> <collector_time>
