Extract string from Given vector string in R

Question

I want to extract city names from all the address given in the vector. address_list=c("802/hiranandani/Mumbai", "2A/kalka-Delhi", "345#near adyar#Chennai", "10-shyaam bazzar-Kolkata")

I tried using strsplit(address_list, c("/","-","#","-"),) function. But it's not giving expected answer. Final answer should be

## [1] "Mumbai"
## [1] "Delhi"
## [1] "Chennai"
## [1] "Kolkata"

Answer 1

Here is a base R solution using gsub

> gsub(".*(\\b\\w+$)","\\1",address_list)
[1] "Mumbai"  "Delhi"   "Chennai" "Kolkata"

---

If you want to print each one, try

> for (i in gsub(".*(\\b\\w+$)","\\1",address_list)) print(i)
[1] "Mumbai"
[1] "Delhi"
[1] "Chennai"
[1] "Kolkata"

Answer 2

Use stringr

> library(stringr)
> str_extract(address_list, '\\w+$')
[1] "Mumbai"  "Delhi"   "Chennai" "Kolkata"
