partitionComparison (version 0.2.3)

registerPartitionVectorSignatures: Make comparison measures usable with any vectors

Description

The comparison measures are defined to use the class '>Partition as parameters. If you do not want to explicitly convert an arbitrary vector of class labels (probably as a result from another package's algorithm) into a '>Partition instance, calling this function will create methods for all measures that allow "ANY" input which is implicitly converted to '>Partition.

Usage

registerPartitionVectorSignatures(e)

Arguments

e

The environment to register the methods in (mostly environment() is fine)

Examples

# NOT RUN {
library(partitionComparison)
randIndex(new("Partition", c(0, 0, 0, 1, 1)), new("Partition", c(0, 0, 1, 1, 1)))
# [1] 0.6
# }
# NOT RUN {
randIndex(c(0, 0, 0, 1, 1), c(0, 0, 1, 1, 1))
# }
# NOT RUN {
# Error in (function (classes, fdef, mtable) :
# unable to find an inherited method for function 'randIndex' for signature '"numeric", "numeric"'
registerPartitionVectorSignatures(environment())
randIndex(c(0, 0, 0, 1, 1), c(0, 0, 1, 1, 1))
# [1] 0.6

# }
