[R] quotes within quotes

[Spencer Graves]

Two ways:

(a) Use single and double qoutes, e.g., "'" is the character string 
consisting of a single apostrophe, while '"' is the character string 
consisting of a single (double) quote mark.

(b) "\"" == '"'; '\'' == "'"

Also, you example suggests you may wish to try "paste".
