### Description

 The package provides efficient and user-friendly functions for creating, manipulating, and subsetting "dist" objects, which are commonly used in clustering applications in R. 
 


The current version includes the following features:    

     

- **Dist2Mat**: Converting a "dist" object to a numeric matrix.

- **subDist2Dist**: Subsetting a "dist" object to a  "dist" object.

- **subDist2Mat**: Subsetting a "dist" object to a numeric "matrix".

- **subCols**: Subsetting a "dist" object to a numeric "matrix" based on some column (equivalently, row) indices.

- **fastDist**: Computing a "dist" object given a numeric matrix.

- **fastDistAB**: Computing a numeric "matrix" storing pairwise distances between rows in two matrices.

- **get2dFrom1d**: Computing 2D-indexing given 1D-indexing (as used in R's "dist" objects).

- **get1dFrom2d**: Computing 1D-indexing given 2D-indexing (a row-column pair).

- **expandDist**: Expanding a "dist" object given new data.

  

Feature(s) under development:   

  

- Providing additional distance functions in fastDist and fastDistAB. The current version only supports popular metrics, namely "euclidean", "manhattan", "minkowski", "maximum", "canberra", and "cosine".

 ### Installation

 To download the newest version of the package, use the following R code: 

```r

library(devtools)
