Check for consistency

The disordR package is designed to make permitted operations transparent and to prevent forbidden operations from being executed.

Function consistent() checks for matching hash codes of its arguments and returns a Boolean. It is called by function check_matching_hash() which either returns TRUE or reports an informative error message if not.

Usage

consistent(x,y)
x %~% y
check_matching_hash(e1,e2,use=NULL)

Arguments

x,y,e1,e2: Objects of class disord
use: optional object designed to give a more intelligible error message; typically match.call()

Details

Function consistent() checks that its arguments have the same hash code, and thus their elements can be paired up (e.g. added). Idiom a %~% b is equivalent to consistent(a,b).

The package generally checks for consistency with function check_matching_hash() which provides some helpful diagnostics if consistent() finds a hash mismatch.

Value

Boolean or an error as appropriate
