Hypothesis-direction helpers

Convenience wrappers for specifying the direction of a hypothesis used by regsen_breakdown() and regsen_bounds().

Usage

bnd_lb(x)

bnd_ub(x)

bnd_eq(x)

Arguments

x

Numeric scalar or vector of hypothesis values.

Value

A numeric vector of the same length as x, carrying a "sign" attribute – ">", "<" or "=" – that tells regsen_breakdown() and regsen_bounds() which direction of hypothesis the values state.

Examples

bnd_lb(0)
#> [1] 0
#> attr(,"sign")
#> [1] ">"
bnd_ub(4)
#> [1] 4
#> attr(,"sign")
#> [1] "<"
bnd_eq(0)
#> [1] 0
#> attr(,"sign")
#> [1] "="
