R help - May 2012 - interactive loop

Dear R-helpers,
I have a number of point configurations representing skull shapes, but
some of them contain superfluous points. I want to write a loop in
which each configuration is plotted and I am asked to write the
numbers of points that are superfluous. However, I don't know how to
introduce this interactive element.
Would you give me an advice?
Best regards
Ond?ej Mikula

I think readline() will do what you want. It can display a message and take user
input, assigning it to a character value so you might need as.numeric()

You might start with par(ask=TRUE) and identify().

A reproducible example might get you actual code. Also, how do you
know they're superfluous? Perhaps that knowledge can be used to
automate identification.
