bit64S3: Turning base R functions into S3 generics for bit64

In truecluster/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
is.double(x)
match(x, table, ...)
x %in% table
rank(x, ...)
order(...)

## Default S3 method:
is.double(x)

## S3 method for class 'integer64'
is.double(x)

## S3 method for class 'integer64'
mtfrm(x)

## Default S3 method:
match(x, table, ...)

## Default S3 method:
x %in% table

## Default S3 method:
rank(x, ...)

## 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()
...	ignored
from	scalar denoting first element of sequence
to	scalar denoting last element of sequence

Details

The following functions are turned into S3 generics in order to dispatch methods for integer64():

• :

• is.double()

• match()

• %in%

• rank()

• 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

Examples

 is.double(as.integer64(1))
    as.integer64(1):9
 match(as.integer64(2), as.integer64(0:3))
 as.integer64(2) %in% as.integer64(0:3)

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


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