You seemed reasonably clear the first time, but you appear not to have  
understood the specific advice that Holtman offered. When someone on  
this list gives you a response like ?text it does not mean they are  
asking you a question. It means you should look at the help page for  
the function text() by typing:

?text

... at the command line. (The brevity may also carry an implication  
that had you offered executable example that there may have been a  
more expansive or explicit answer. The ?<something> reply is an effort  
to be slightly more helpful than RTFM.)
