identical_partition {diffval}

Do the vectors represent the same k-partition?

Description

Checks if two vectors represent the same k-partition.

Usage

identical_partition(p1, p2)

Arguments

p1

A vector of integers representing a k-partition (taking values from 1 to k), of the same length of p2.

p2

A vector of integers representing a k-partition (taking values from 1 to k), of the same length of p1.

Details

Parameters p1and p2are vectors indicating group membership. In this package context, these vectors have as many elements as the columns of a phytosociological table, indicating the group membership of each relevé to one of k groups (i.e., a k-partition). This function checks if the two given vectors p1and p2 correspond, in practice, to the same k-partition, i.e., if the relevé groups are actually the same, but the group numbers are somehow swapped.

Value

TRUE if p1and p2 represent the same k-partitions; FALSE otherwise.

Examples

# Creating three 2-partitions
par1 <- c(1, 1, 2, 2, 2)
par2 <- c(2, 2, 1, 1, 1)
par3 <- c(1, 1, 1, 2, 2)

# Is it the same partition?
identical_partition(par1, par2) # TRUE
identical_partition(par1, par3) # FALSE
identical_partition(par2, par3) # FALSE
