Thanks....Didn't mean actually using '&', but not bigger than that too...
I usually see something done much better in R-help by a code which I don't know at all. So, wanted to know if I am missing somewhere in using some codes which I am not aware of...so, posted the query...

But was just wondering if there existed a simple tricky command for that without using the & condition.... Also was thinking on my second question that how do we define an interval between 0 and 1 which contains all the values between 0 and 1.

For example: C(0,1) is incorrect, seq(0,1,0.2) is also incorrect, seq(0,1,0.00001) is also incorrect.... How does one specify this?

And I can't use a single statement like > (0<C<1). Is there a between function? Or how do we specify from 0 to 1? > Does %in% help me? If you don't like (C > 0 && C < 1), then just write your own function is.between(x, low, high) (NB1 you've basically written it already; NB2 single '&' for the vectorised version 'are.between'). People's personal tastes about what's desirable will vary, and anyway it's good practice to build up your own personal library of functions. Ultimately if you have a high quality collection of related functions for working on a particular sort of problem, then you should publish them as an R package on CRAN.
