Test if scalar is in interval

is.scalar_in(left, right)

is.scalar_in01(x)

Arguments

left, right	lower and upper bound
x	R object to be tested, most likely a numeric vector of length one (other formats are allowed but will always return `FALSE`).

Value

is.scalar_in01 returns TRUE if x is an atomic vector of length one and 0 <= as_numeric(x) <= 1. is.scalar_in return a function similar to is.scalar_in01 but with specified boundaries.

Examples

is.scalar_in01(.5) # TRUE
#> [1] TRUE
is.scalar_in01(5) # FALSE
#> [1] FALSE

is_scalar_in09 <- is.scalar_in(0,9)
is_scalar_in09(5) # TRUE
#> [1] TRUE
