is_true: Convert a logical Array to a Binary Boolean Array

Description

I often use mathematical expressions to index data by its values. But when the data contain missing values, the logical indices do not index the data, so I need to convert them to boolean.

Usage

is_true(x)

Value

A binary boolean array indicating where the logical

array is TRUE.

Arguments

x

An logical array, probably the result of some kind of mathematical expression.

Examples

x <- array(1:24, dim = c(2,3,4))
x[2,2,3] <- NA
print(x)
x < 20 # An array containing NA
is_true(x < 20) # An array boolean only, NA converted to FALSE
print(x <- x[2, TRUE, TRUE])
is_true(x < 20) # A matrix
x <- x[2, TRUE]
is_true(x < 20) # A vector
x <- x[3]
is_true(x < 20) # A scalar
