Usage

find_less(x, choices, include_same = TRUE, none = c("first", "na"))

Arguments

x: The vector of values to select choices for.
choices: The choices that are to be selected from.
include_same: Include if the choice is <= and not strictly <.
none: What if the x value is less than (or less than or equal to if include_same) all the choices? Choose the "first" choice or insert an NA value?

Value

A vector with values from choices that are less than (or equal to) x

Details

x and choices must be comparable by the < or <= operators. choices will be sorted to be in ascending order; sorting will remove any NA values from choices.
