Convert numbers to adverbial character vectors (once, twice, three times)

Description

Convert numbers to adverbial character vectors (once, twice, three times)

Usage

adverbial(x, thrice = FALSE, ...)

nom_adv(x, thrice = FALSE, ...)

nom_times(x, thrice = FALSE, ...)

Arguments

x	A numeric vector
thrice	A logical of length one. If TRUE, the adverbial of 3 will be "thrice". If FALSE, the adverbial of 3 will be "three times". Defaults to FALSE.
...	Additional arguments passed to cardinal()

Value

A character vector of the same length as x

See Also

Other number names: cardinal(), collective(), denominator(), numerator(), ordinal(), ratio()

Examples

nom_adv(1:4)
nom_adv(1:4, thrice = TRUE)

Convert numbers to cardinal character vectors (one, two, three)

Description

Convert numbers to cardinal character vectors (one, two, three)

Usage

cardinal(x, max_n = Inf, negative = "negative", ...)

nom_card(x, max_n = Inf, negative = "negative", ...)

Arguments

x	A numeric vector
max_n	A numeric vector. When the absolute value of x is greater than max_n, x remains numeric instead of being converted to words. If max_n is negative, no xs will be converted to words. (This can be useful when max_n is passed by another function.) Defaults to Inf, which converts all xs to words.
negative	A character vector to append to negative numbers. Defaults to "negative".
...	Arguments passed on to fracture::frac_mat denom If denom is not NULL, all fractions will have a denominator of denom. This will ignore all other arguments that affect the denominator. base_10 If TRUE, all denominators will be a power of 10. common_denom If TRUE, all fractions will have the same denominator. If the least common denominator is greater than max_denom, max_denom is used. max_denom All denominators will be less than or equal to max_denom. If base_10 is TRUE, the maximum denominator will be the largest power of 10 less than max_denom. A max_denom greater than the inverse square root of machine double epsilon will produce a warning because floating point rounding errors can occur when denominators grow too large.

Value

A character vector of the same length as x

Fractions

Decimal components of x are automatically converted to fractions by fracture::frac_mat().

Convert numbers to collective character vectors (the, both, all three)

Description

Convert numbers to collective character vectors (the, both, all three)

Usage

collective(x, all_n = TRUE, of_the = FALSE, cardinal = TRUE, ...)

nom_coll(x, all_n = TRUE, of_the = FALSE, cardinal = TRUE, ...)

Arguments

x	A numeric vector.
all_n	Whether to include the cardinal number after "all" for collectives of 3 or more. Defaults to TRUE.
of_the	Whether to include "of the" for collectives other than 1. Defaults to FALSE.
cardinal	Whether to convert the number after "all" with cardinal() when all_n is TRUE. Defaults to TRUE.
...	Additional arguments passed to cardinal() when cardinal is TRUE.

Value

A character vector of the same length as x.

See Also

Other number names: adverbial(), cardinal(), denominator(), numerator(), ordinal(), ratio()

Examples

paste(nom_coll(0:3), "fish")
paste(nom_coll(9:12, max_n = 10), "fish")

---

Convert numbers to denominator character vectors (whole, half, third)

Description

Convert numbers to denominator character vectors (whole, half, third)

Usage

denominator(x, numerator = 1, quarter = TRUE, ...)

nom_denom(x, numerator = 1, quarter = TRUE, ...)

Arguments

x	A numeric vector
numerator	A numeric vector. The numerator(s) associated with the denominator(s). When numerator is not 1 or -1, the denominator will be pluralized.
quarter	A logical of length one. If TRUE, the denominator of 4 will be "quarter(s)". If FALSE, the denominator of 4 will be "fourth(s)". Defaults to TRUE.
...	Additional arguments passed to ordinal()

Value

A character vector of the same length as x

See Also

Other number names: adverbial(), cardinal(), collective(), numerator(), ordinal(), ratio()

Examples

nom_denom(2)
nom_denom(1:10)
nom_denom(1:10, numerator = 2)
nom_denom(1:10, numerator = 1:10)

nom_denom(4)
nom_denom(4, quarter = FALSE)

nom_denom(1:10, numerator = 2, cardinal = FALSE)
nom_denom(5:15, numerator = 2, max_n = 10)

---

Convert numbers to numerator character vectors (one, two, three)

Description

nom_numer() and numerator() are equivalent to nom_card() and cardinal() for integers, but cardinals support fractional components while numerators do not.

Usage

numerator(x, ...)

nom_numer(x, ...)

Arguments

x	A numeric vector
...	Additional arguments passed to cardinal()

See Also

Other number names: adverbial(), cardinal(), collective(), denominator(), ordinal(), ratio()

Convert numbers to ordinal character vectors (first, second, third)

Description

Adds ordinal suffixes to numbers (or a character vector of number-like words). Converts numeric vectors to cardinal numbers before adding prefixes unless cardinal is FALSE.

Usage

ordinal(x, cardinal = TRUE, ...)

nom_ord(x, cardinal = TRUE, ...)

Arguments

x	A numeric or character vector.
cardinal	Whether to convert a numeric vector with cardinal() before applying ordinal suffixes. When TRUE, 1 -> "first". When FALSE, 1 -> "1st". Defaults to TRUE.
...	Further arguments passed to cardinal() when cardinal is TRUE.

Value

A character vector of the same length as x

See Also

Other number names: adverbial(), cardinal(), collective(), denominator(), numerator(), ratio()

Examples

nom_ord(2)

nom_ord(9 + 3/4)

---

Convert numbers to ratio character vectors (two to one, one in three, five out of ten)

Description

Convert numbers to ratio character vectors (two to one, one in three, five out of ten)

Usage

ratio(x, sep = "in", max_n = Inf, negative = "negative", ...)

nom_ratio(x, sep = "in", max_n = Inf, negative = "negative", ...)

Arguments

x	A numeric vector
sep	A character vector separating components of the ratio. Defaults to "in".
max_n	A numeric vector. When the absolute value of x is greater than max_n, x remains numeric instead of being converted to words. If max_n is negative, no xs will be converted to words. (This can be useful when max_n is passed by another function.) Defaults to Inf, which converts all xs to words.
negative	A character vector to append to negative numbers. Defaults to "negative".
...	Arguments passed on to fracture::frac_mat denom If denom is not NULL, all fractions will have a denominator of denom. This will ignore all other arguments that affect the denominator. base_10 If TRUE, all denominators will be a power of 10. common_denom If TRUE, all fractions will have the same denominator. If the least common denominator is greater than max_denom, max_denom is used. max_denom All denominators will be less than or equal to max_denom. If base_10 is TRUE, the maximum denominator will be the largest power of 10 less than max_denom. A max_denom greater than the inverse square root of machine double epsilon will produce a warning because floating point rounding errors can occur when denominators grow too large.

Details

x is converted to a fraction by fracture::frac_mat().

Value

Usage

uncardinal(x)

nom_uncard(x)

Arguments

x	A character vector of the cardinal names of numbers

Value

A numeric vector the same length as n. NAs will be produced for numbers with fractions or decimals or non-cardinal numbers (e.g. ordinals).

Examples

  c(
    "twenty-five",
    "one million two hundred thirty-four thousand five hundred sixty-seven"
  )
)
uncardinal("infinity")
