bit64S3: Turning base R functions into S3 generics for bit64

In bit64: A S3 Class for Vectors of 64bit Integers

Turning base R functions into S3 generics for bit64

Description

Turn those base functions S3 generic which are used in bit64

Usage

	from:to
 #--as-cran complains about \method{:}{default}(from, to)
 #--as-cran complains about \method{:}{integer64}(from, to)
	is.double(x)
 ## Default S3 method:
is.double(x)
 ## S3 method for class 'integer64'
is.double(x)
	match(x, table, ...)
 ## Default S3 method:
match(x, table, ...)
	x %in% table
 ## Default S3 method:
x %in% table
	rank(x, ...)
 ## Default S3 method:
rank(x, ...)
	
 
	order(...)
 ## Default S3 method:
order(...)

Arguments

x	integer64 vector: the values to be matched, optionally carrying a cache created with hashcache
table	integer64 vector: the values to be matched against, optionally carrying a cache created with hashcache or sortordercache
from	scalar denoting first element of sequence
to	scalar denoting last element of sequence
...	ignored

Details

The following functions are turned into S3 gernerics in order to dispatch methods for integer64:

	   \code{\link{:}}
	   \code{\link{is.double}}
	   \code{\link{match}}
	   \code{\link{%in%}}
	   
	   \code{\link{rank}}
	   \code{\link{order}}
   

Value

invisible

Note

is.double returns FALSE for integer64
: currently only dispatches at its first argument, thus as.integer64(1):9 works but 1:as.integer64(9) doesn't match currently only dispatches at its first argument and expects its second argument also to be integer64, otherwise throws an error. Beware of something like match(2, as.integer64(0:3)) %in% currently only dispatches at its first argument and expects its second argument also to be integer64, otherwise throws an error. Beware of something like 2 %in% as.integer64(0:3) order currently only orders a single argument, trying more than one raises an error

 unique(as.integer64(c(1,1,2)))
 rank(as.integer64(c(1,1,2)))
 
 
 
 
 
 
 order(as.integer64(c(1,NA,2)))
