Not to define a vector of all infinite values... But if I have some object (may not be a vector) which has this interval, then I can apply whatever function I need to on this interval apart from 'between' function... Is there something like that... Hope I am clear with the idea...

Obviously you can't explicitly construct an infinitely large vector in R. If you want to construct an implicit specification of that set, then I think I've already given you a good answer in R: define a predicate function and use it. E.g. between <- function(x, low, high) x > low && x < high I don't know much at all about symbolic mathematics packages like Maple and Mathematica, but maybe you're thinking of something you can do in those softwares? R is not trying to be a competitor to them; they do lots of things R doesn't, and vice versa.
