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

# rdis() + rdis() # this would make check_matching_hash() report an error, if executed
