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.
You can install the released version of motif from CRAN with:
install.packages("motif")And the development version from GitHub with:
# install.packages("remotes")
remotes::install_github("Nowosad/motif")See the package’s vignettes:
- Introduction to the motif package
- Types of spatial patterns’ signatures
- Spatial patterns’ search
- Spatial patterns’ comparision
- Spatial patterns’ clustering
- Extracting the proportion of different classes in many regular local landscapes
