How to step through a demo

I have just started to learn R on linux in an X-terminal  "command line" 
environment at the R prompt ">".  When I try to run a demo it just races 
through all the steps and graphics leaving me with only the last few 
commands and results in the  terminal window and a window with the last 
graphic.  Is there a way to step through the demo command-by-command 
graphic-by-graphic, or, if not, how should I make use of (i.e. run) the 
demo? 

Thanks for any help

Dear Prof. Ripley: 

      Thanks for this. 

      What would need to happen to get this added to "see also" in the 
"demo" help page? 

      Thanks again,
      Spencer Graves

You need to convince a member of the R core team to add it.  Doing that 
is easiest if you do all the work:  figure out which files need 
modifying, and write reasonable modifications.  (For "reasonable", I 
mean something that explains to a reader why s/he would want to follow 
the link.)  Part of the work in making a change like this is thinking 
about where to make it:  it doesn't make much sense to me to add it just 
to the ?demo page but not the ?example page, for instance.  Should it go 
somewhere else too?

The format of what you should post is less clear:  some core members 
like patch files, I prefer an explanation of what to change.  Where to 
post is generally fairly easy to guess:  follow up on a thread like 
this, and if you don't get a response and the change doesn't get made, 
post the suggestion in its own thread on R-devel.  And if you do get a 
negative response, don't worry about it too much:  your posting on the 
public mailing list will be part of the documentation that RSiteSearch() 
will find, so you will have added value anyway.

(This message is neither a positive nor a negative response to the 
actual suggestion:  I think I'd be happy to make this addition if you do 
the work, but I probably won't get around to doing the work if you don't.)
