Experimental class "disindex"
disindex-class.Rd
Experimental disindex
class provides a disordR
-compliant
method for indexing disord
objects. The idea is that
which(x)
, where x
is Boolean of class disord
,
should have meaning under disordR
discipline. Thus
which()
gives a disindex
object. This object can be
used as an index for other disord
objects. One application
would be the dismat
class of matrices, currently under
development.
Function values()
coerces its argument to an integer vector.
Objects from the Class
Objects can be created by calls of the form new("disindex", ...)
,
although which()
is more natural.
Examples
(x <- disord(c(1,2,1,2,2,7)))
#> A disord object with hash 26d0d11f32710d12dc5ec568e9714aade9b452a7 and elements
#> [1] 1 2 1 2 2 7
#> (in some order)
x==2
#> A disord object with hash 26d0d11f32710d12dc5ec568e9714aade9b452a7 and elements
#> [1] FALSE TRUE FALSE TRUE TRUE FALSE
#> (in some order)
w <- which(x==2)
w
#> A disind object with hash 26d0d11f32710d12dc5ec568e9714aade9b452a7 and 3 (implementation-specific) elements
x[w] <- 100
x
#> A disord object with hash 0c237cab646c71c0ddb67807cb90e6a5ac6b8e47 and elements
#> [1] 1 100 1 100 100 7
#> (in some order)
