Extracting the last n characters from a string in R

Question

How can I get the last n characters from a string in R? Is there a function like SQL's RIGHT?

Answer 1

To extract last n characters from a string, you can use the str_sub function from the stringi package as follows:

stri_sub(x,i,n)

Where

x  - String/Vector

i  - Start index

n  - Final index

For example:

library("stringi") 

vec <- c("Hello World") 

str <- stri_sub(vec,-5,-1) 

str 

Output: 

[1] "World"
