Part 2: Includes code to get NRI values for PT2, as well as GBIF data needed to run code

<b>WARNING: This code takes a very, very long time to run (~20 minutes- 1 hour per country). Running this code is NOT necessary to check the code in PTS-2-3-Analysis-022825.</b><b>The R script to calculate NRI is </b><b>NRI-PT2-022825</b>For six globally distributed invasive plants, we determined which countries the plant was invasive in using GRIIS (link: GRIIS.org/). We then went to GBIF and looked at all the global observations and went country by country and drew a rectangle over 70%+ of the country's observations (which we refer to as the area most densely invaded). We downloaded those observations, along with all the plant observations in the same space, with appropriate restrictions (year, quality, human observations, etc). The GBIF data are available in figshare, as are the citations. We then randomly chose transects within each country and made a list of all the plants in each transect. I then followed this tutorial (https://pedrohbraga.github.io/CommunityPhylogenetics-Workshop/CommunityPhylogenetics-Workshop.html) to calculate the NRI of each of the transects.b. Ultimately, the result of this file is a series of csvs (uploaded to figshare) that include the NRI values for each transect (across all plants).<br><b>To run this code, you need the GBIF data used. </b>The GBIF citations include a DOI where you can access/download the data. The GBIF citations can be found in figshare (labeled GBIF Citations), but also in the supplementary materials.NOTE: Many of the GBIF files are too large to directly upload. In the figshare folder, in addition to the citations where you can access ALL the data by downloading each one individually, I have uploaded a sample of csvs that are ready for use.<b> In other words, access to all the GBIF data is in the GBIF Citations doc, but I have also put in a couple of example GBIF csvs as well.</b>I am more than happy to send the csvs (along with their GBIF citations) directly to people, however, it would need to be via a site that allows the transfer of large files.
