### gower

Gower's distance for R. Based in C, using openMP for parallelization.

### Usage

```

library(gower)

reviris <- iris[rev(seq_len(nrow(iris))),,drop=FALSE]

# compute distances

d <- gower_dist(iris, reviris)

# data.frame with less records is recycled

d <- gower_dist(iris[1:3,,drop=FALSE], reviris)

# compute top-n matches

mat <- gower_topn(iris, reviris, n=5)

## mat$index   : Array of indices (sorted from better to worse match)

## mat$distance: Array of distances (sorted from small to large)

```

### Installation

#### From CRAN

```

install.packages("gower")

```

#### Beta versions

Made available through my drat repo.

```

if(!require(drat)) install.packages('drat')

drat::addRepo('markvanderloo')

install.packages('gower',type='source')
