Extract words between doubles quotes in a variable in R

I want to extract the name from the following input which is of the form as shown in brackets

# Example of the input in brackets('name":"Tale")
name<- c('name":"Tale"','name":"List"')

I want to extract the names between the quotes as shown below. Any suggestions?

name
Tale
List

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

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
