Convert Number to Words in R Data Frame Column

To convert number to words in an R data frame column, we can use english function from english package. For example, if we have a data frame called df that contains a number column x then we can convert the numbers into words by using the command as.character(english(df$x)).

Example

Consider the below data frame −

 Live Demo

x<-rpois(20,5)
df1<-data.frame(x)
df1

Output

    x
1   3
2   5
3   4
4   7
5   7
6   3
7   6
8   1
9  11
10  6
11  6
12  6
13  5
14  7
15  4
16  1
17  3
18  1
19  1
20  1

Loading english package and converting numbers in column x to words −
