Or at least anyways of defining a vector/(or something like that) which
has all 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?
Thanks, Shubha

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.
