The **motif** package implements and extends ideas of the pattern-based spatial analysis in R.

It describes spatial patterns of categorical raster data for any defined regular and irregular areas. 

Patterns are represented quantitatively using built-in signatures based on co-occurrence matrices but also allows for any user-defined functions. 

It enables spatial analysis such as search, change detection, and clustering to be performed on spatial patterns.

## Installation

You can install the released version of motif from [CRAN](https://CRAN.R-project.org) with:

``` r

install.packages("motif")

```

And the development version from [GitHub](https://github.com/) with:

``` r

# install.packages("remotes")

remotes::install_github("Nowosad/motif")

```
