Screen which element is within a range in R

Question

I would like to ask if there is a way to check for example

c(13, 20, 1, 5, 40, 15, 6, 8)

is within a range e.g. > 5 and <= 30 will give output like below:

[1] TRUE TRUE FALSE FALSE TRUE TRUE TRUE

Answer 1

Isn't it just this?

x <- c(13, 20, 1, 5, 40, 15, 6, 8)
x > 5 & x <= 30
#[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

We can also use between from dplyr or data.table but this includes upper and lower boundaries so we can do

dplyr::between(x, 6, 31)
#[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Or

data.table::between(x, 6, 31)

Answer 2

First of all you omitted a FALSE in your expected result. But you can achieve that by doing this :

c <- c(13, 20, 1, 5, 40, 15, 6, 8)
a <- c > 5 & c <= 30
print(a)
