## match_evaluate_multiple

### Description

Function to match cluster labels with 'true' clusters using the Hungarian algorithm, and return precision, recall, and F1 score. Written by Lukas Weber in August 2016 as part of his cytometry clustering comparison, with just slight modifications on initial handling of input arguments.

### Usage

    match_evaluate_multiple(clus_algorithm, clus_truth = NULL)

### Arguments

`clus_algorithm` | cluster labels from algorithm
`clus_truth` | true cluster labels. If NULL, will attempt to read them from the names of 'clus_algorithm' (expecting the format 'clusterName.cellName')

### Value

A list.

### Examples

    # random data
    dat <- data.frame(
     cluster=rep(LETTERS[1:3], each=10),
     x=c(rnorm(20, 0), rnorm(10, 1)),
     y=c(rnorm(10, 1), rnorm(20, 0))
    )
    # clustering
    dat$predicted <- kmeans(dist(dat[,-1]),3)$cluster
    # evaluation
    match_evaluate_multiple(dat$predicted, dat$cluster)
