Parse logicals, integers, and reals

Use parse_*() if you have a character vector you want to parse. Use col_*() in conjunction with a read_*() function to parse the values as they're read in.

Usage
parse_logical(x, na = c("", "NA"), locale = default_locale())

parse_integer(x, na = c("", "NA"), locale = default_locale())

parse_double(x, na = c("", "NA"), locale = default_locale())

parse_character(x, na = c("", "NA"), locale = default_locale())

col_logical()

col_integer()

col_double()

col_character()

Arguments
x
Character vector of values to parse.
na
Character vector of strings to use for 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.

Examples
parse_integer(c("1", "2", "3"))
parse_double(c("1", "2", "3.123"))
parse_number("$1,123,456.00")

# Use locale to override default decimal and grouping marks
es_MX <- locale("es", decimal_mark = ",")
parse_number("$1.123.456,00", locale = es_MX)

# Invalid values are replaced with missing values with a warning.
x <- c("1", "2", "3", "-")
parse_double(x)
# Or flag values as missing
parse_double(x, na = "-")
