[R] extracting text from wordnet using synonym()

[Kelvin Lam]

Dear group,

There are postings on extracting partial string using sub()/gsub()/gsubfn()
but I still couldn't figure this one out.  Supposed I am pulling the
synonyms of "help" using synonyms("help") from wordnet and get the
followings:

> synonyms("help")
[1] "c(\"aid\", \"assist\", \"assistance\", \"help\")"     
[2] "c(\"aid\", \"assistance\", \"help\")"                 

How can I get a one character string at the end that looks like this:

[1] "aid" "assist" "assistance" "help" "aid" "assist" "help" 

Thanks for the help!!!!!

Kelvin
