Experimental class "disindex"

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.

Slots

value:

Numeric vector

hash:

Object of class character that specifies the hash code

Examples

(x <- disord(c(1,2,1,2,2,7)))
#> A disord object with hash 474973473eec4162918f7e44ff21e84217583751 and elements
#> [1] 1 2 1 2 2 7
#> (in some order)

x==2
#> A disord object with hash 474973473eec4162918f7e44ff21e84217583751 and elements
#> [1] FALSE  TRUE FALSE  TRUE  TRUE FALSE
#> (in some order)
w <- which(x==2)
w
#> A disind object with hash 474973473eec4162918f7e44ff21e84217583751 and 3 (implementation-specific) elements

x[w] <- 100
x
#> A disord object with hash b826546bba924a2de3fc1f76de48ac3cf29bf4fe and elements
#> [1]   1 100   1 100 100   7
#> (in some order)
