h_in_range: Check which elements are in a given range

In Roche/crmPack: Object-Oriented Implementation of CRM Designs

Check which elements are in a given range

Description

A simple helper function that tests whether elements of a given vector or matrix are within specified interval.

Usage

h_in_range(x, range = c(0, 1), bounds_closed = TRUE)

Arguments

x	(numeric) vector or matrix with elements to test.
range	(numeric) an interval, i.e. sorted two-elements vector.
bounds_closed	(logical) should bounds in the range be treated as closed? This can be a scalar or vector of length two. If it is a scalar, then its value applies to lower bound range[1] and upper bound range[2]. If this is a vector with two flags, the first flag corresponds to the lower bound only, and the second to the upper bound only.

Value

A logical vector or matrix of length equal to the length of x, that for every element of x, indicates whether a given element of x is in the range.

Examples

x <- 1:4
h_in_range(x, range = c(1, 3))
h_in_range(x, range = c(1, 3), bounds_closed = FALSE)
h_in_range(x, range = c(1, 3), bounds_closed = c(FALSE, TRUE))
mat <- matrix(c(2, 5, 3, 10, 4, 9, 1, 8, 7), nrow = 3)
h_in_range(mat, range = c(1, 5))
