Do values in a numeric vector fall in specified range?

Source: R/funs.R

This is a shortcut for x >= left & x <= right, implemented efficiently in C++ for local values, and translated to the appropriate SQL for remote tables.

between(x, left, right)

Arguments

x

A numeric vector of values
left, right

Boundary values (must be scalars).

Examples

between(1:12, 7, 9)

#>  [1] FALSE FALSE FALSE FALSE FALSE FALSE  TRUE  TRUE  TRUE FALSE FALSE FALSE

x <- rnorm(1e2)
x[between(x, -1, 1)]
