SQL has a between operator and via sqldf you can do this using
the built in data frame BOD as an example:
> library(sqldf)
> BOD
Time demand
118.3
22 10.3
33 19.0
44 16.0
55 15.6
67 19.8
> sqldf("select demand between 15 and 17 from BOD")
demand between 15

Here is how you check whether a < x < b "without" using the `&' condition:
is.between <- function(x, a, b) {
(x - a) * (b - x) > 0
}

Hi Shubaa,
Here is one way to do this:
is.between <- function(x, a, b) {
x > a & x < b
}
set.seed(123)
x <- rnorm(5)
is.between(x, -1, 1)
> is.between(x, -1, 1)
[1] TRUE TRUE FALSE TRUE TRUE

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

Hi R,
This is a very trivial one
C=0.1
I want to check whether my value of C is between 0 and 1 exclusively
I don't want to use (C>0 & C<1). And I can't use a single statement like
