创建一个用字母写的数字序列

Question

How can I create a sequence of numbers but those numbers should be written in letters, ie "one" instead of 1 / "two" instead of 2. I want to create a vector of numbers from 100 to 1 (in reverse order) and the numbers need to be written in letters. TIA

Answer 1

You can use the english package for this.

library(english)

as.english(100:1)

[1] one hundred   ninety nine   ninety eight  ninety seven  ...  

Or for character output:

words(100:1) 

[1] "one hundred"   "ninety nine"   "ninety eight"  "ninety seven" ...

Edit: As neilfws notes words() will produce character strings which might be more useful if you want to continue to process the data. as.english() is a print/format method.

Answer 2

Copy and paste this R function .

Then run:

numbers2words(100:1)

Testing using 10 to 1 (100 to 1 works, but I didn't want to paste the large output here):

numbers2words(10:1)

 [1] "ten"   "nine"  "eight" "seven" "six"   "five"  "four"  "three" "two"   "one"  

EDIT: better still use english::words(100:1) as in the answer from H 1.
