R scripts and data files

The uploaded files on Figshare include the data and R scripts for data filtering, the GAM/qGAMs and Random Forest analyses, implemented in the manuscript Wagner et al. (2021) <b>Alien plant invasion hotspots and invasion debt in European woodlands.</b><br> Not included are the extraction and preparation of predictor and response variables (given that some variables had to be prepared in QGIS and ArcGIS), the R script for preparing Fig. 1 (map) and data summary tables (since these can be easily produced). These excluded files, however, can be requested from the first author ([e-mail]). <br> The data include only the most essential data from the European Vegetation Archive. To retrieve more information for plots, including species abundances, permission must be requested from the individual Custodians (for more information, contact [e-mail]).<br>Check the Readme.txt file for meta-data.
