"\n" does NOT "skip to the next line". It is a character and it is  
interpreted by some sort of program, say a a plotting program or a  
word-processor as a line feed. You need to specify what sort of  
program you intend to do this "skipping-to-next-page" action and also  
provide the character sequence that that program uses to signal that  
action. (There are not any pages in R except perhaps multi-page plots  
but you seem to be in character mode at the moment.)
