Check Less Than or Equal To

Checks if all non-missing values are less than or equal to y using

all(x[!is.na(x)] <= value)

Usage

chk_lte(x, value = 0, x_name = NULL)

vld_lte(x, value = 0)

Arguments

x

The object to check.

value

A non-missing scalar of a value.

x_name

A string of the name of object x or NULL.

Value

The chk_ function throws an informative error if the test fails or returns the original object if successful so it can used in pipes.
