r - convert names to character strings -

this question has answer here:

i came across meta-programming task seemed must have obvious , simple answer, not find one.

i have bunch of names wrapped in ():

(foo, bar, buzz, zap)

i want convert these names character vector:

("foo", "bar", "buzz", "zap")

the fastest come follows:

as.character(quote(c(foo, bar, buzz, zap)))[-1] # "foo"  "bar"  "buzz" "zap"

i've got imagine there's cleaner solution.

edit

possible duplicate, different title hard discover: does r have quote-like operators perl's qw()?

a. option1

 k<-"(foo, bar, buzz, zap)"     strsplit(strsplit(k,"\\(|\\)")[[1]][2],", ")[[1]]     [1] "foo"  "bar"  "buzz" "zap"

b. option 2

library(stringr) str_extract_all(k,"[aa-zz]+")[[1]] #assuming contains letters [1] "foo"  "bar"  "buzz" "zap"
