EqualsEquals: For testing equivalence of numbers.

In jgrevel/BAST1-R-Library: BAST R function library.

Description

Operator that is similar to ==, for comparing two numeric vectors.

Usage

a %==% b

Arguments

a	numeric vector to be tested for equivalence.
b	numeric vector to be tested against a for equivalence.

Details

This operator works with the option insigbits, which should be an integer between 1 and 8. The option insigbits defines how many bits (from least significant) will be considered as insignificant in deciding upon equality.

Value

TRUE if all but the insignificant parts are identical.

Note

Default for insigbits is 6, it can be changed by using

options(insigbits = #),

where # is the desired value.
