Your command includes (at about character position 240): 'R.N.S.1ST',R.N.S.2ND' Note the missing quote after the comma.
When R's error message starts with Error: instead of Error in <command>: it usually means it could not parse the text that you typed to make a command out of it. (Perhaps it should say 'Error while parsing input text'.)
