I created the quadcleanR R package to assist in standardizing quadrat areas while maintaining the spatial relationships between identified organisms and substrates. There are also many functions to help with the cleanup and visualization of quadrat data.
These new functions are important to ensure that quadrat data are properly standardized, to allow for large scale analyses to occur so that we can better understand how diversity is changing around the world
Additionally there is a function to produce a Shiny app so that quadrat data can interactively explored. A sample data set is provided in the package, but any quadrat or quadrat-like data can be used.
