We could use stri_extract_last_words

library(stringi)
library(data.table)
setDT(list(name=stri_extract_last_words(name)))[]
#   name
#1: Tale
#2: List

I have been going through stringi manual again since yesterday. You are too fast, as usual. :) – jazzurro Nov 26 '15 at 03:01
@jazzurro Thanks for the comment and vote. There are handy functions in that package. – akrun Nov 26 '15 at 03:04
Yeah, I have been using some of them to handle string extraction for a data set. Fast speed. – jazzurro Nov 26 '15 at 03:07

Convert the vector to a single column data.frame, and then just use gsub to remove the name": and " from the string.

Example:

transform(data.frame(name), name = gsub("name\":|\"", "", name))
##   name
## 1 Tale
## 2 List
