nombre

nombre (French) /nɔ̃bʁ/: number
nombre (Spanish) /ˈnom.bɾe/: name
nombre: package to convert numbers to their names in R

nombre converts numeric vectors to character vectors of English words. You can use it to express numbers as cardinals (one, two, three) or ordinals (first, second, third), as well as numerators and denominators. nombre supports not just whole numbers, but also negatives, fractions, and ratios.

Installation

You can install the released version of nombre from CRAN with:

install.packages("nombre")

or the development version from GitHub with:

# install.packages("remotes")
remotes::install_github("rossellhayes/nombre")

Usage

nombre converts numerics into words:

nom_card(2)
#> [1] "two"
nom_card(2L)
#> [1] "two"
x <- rep(TRUE, 525600)
nom_card(length(x))
#> [1] "five hundred twenty-five thousand six hundred"

It also works for numeric vectors:

nom_card(8^(1:10))
#>  [1] "eight"                                                                                       
#>  [2] "sixty-four"                                                                                  
#>  [3] "five hundred twelve"                                                                         
#>  [4] "four thousand ninety-six"                                                                    
#>  [5] "thirty-two thousand seven hundred sixty-eight"                                               
#>  [6] "two hundred sixty-two thousand one hundred forty-four"                                       
#>  [7] "two million ninety-seven thousand one hundred fifty-two"                                     
#>  [8] "sixteen million seven hundred seventy-seven thousand two hundred sixteen"                    
#>  [9] "one hundred thirty-four million two hundred seventeen thousand seven hundred twenty-eight"   
#> [10] "one billion seventy-three million seven hundred forty-one thousand eight hundred twenty-four"

nombre can also generate ordinals, adverbials, collectives, numerators and denominators:

nom_ord(1:5)
#> [1] "first"  "second" "third"  "fourth" "fifth"
nom_adv(1:5)
#> [1] "once"        "twice"       "three times" "four times"  "five times"
nom_coll(1:5)
#> [1] "the"       "both"      "all three" "all four"  "all five"
nom_numer(1:5)
#> [1] "one"   "two"   "three" "four"  "five"
nom_denom(1:5)
#> [1] "whole"   "half"    "third"   "quarter" "fifth"
nom_denom(1:5, numerator = 1:5)
#> [1] "whole"    "halves"   "thirds"   "quarters" "fifths"
