Replace last comma in character with “ &”

Category:Languages

I have many different characters which have the following structure:

# Example x <- "char1, char2, char3" 

I want to remove the last comma of this character with " &", i.e. the desired output should look as follows:

# Desired output "char1, char2 & char3" 

How could I replace the last comma of a character with " &"?

 


One option is stri_replace_last from stringi

library(stringi) stri_replace_last(x, fixed = ',', ' &') #[1] "char1, char2 & char3"
