This workflow demonstrates how to import your own point data (occurrences) and
SDMs (rasters), check all inputs, and run the full gap analysis for **multiple
species** using the GapAnalysis R package. We provide a general approach using
a for-loop for processing and storing results for multiple species. Example
*Cucurbita* data is provided within the package library.

> **Note:** This vignette recommends [**R version 4.5**](https://cran.r-project.org/) or above. Windows users are also recommended to have [**Rtools 4.5**](https://cran.r-project.org/bin/windows/Rtools/) or above installed.

**For each species, the workflow:**

1. Runs SRSex on all records.
2. Checks inputs (occurrences, rasters, protected areas, ecoregions).
3. Runs gap analysis metrics.
4. Stores results as a table to an output excel file.
5. Creates a conservation priority summary figure as an output png file.
6. Generates interactive leaflet maps for both ex-situ and in-situ conservation as output HTML files.

At script end, the user is prompted to save the workflow by knitting to output HTML.

## Download GapAnalysis repository *(ALTERNATIVE)*

Copy the GapAnalysis GitHub repository locally as an alternative method to
source functions and load example data **if the GapAnalysis R package does not
install properly in the step above**. See the
[GitHub resource page](https://docs.github.com/en/get-started/start-your-journey/downloading-files-from-github)
on copying a repository.

> **Easiest method:** Download and extract the
> [GapAnalysis repository](https://github.com/CIAT-DAPA/GapAnalysis/tree/master).
> Select the green [**Code**] button on the main page to download as a ZIP.
>
> You can also clone the repository if you have a GitHub account.

removing the hashes below. Your specific path will differ based on your working
directory and the relative path to the downloaded repository.

## Run gap analysis

Example gap analysis workflow using a named list and for-loop to process and
store results for all species. 

**For details on each metric calculation, review the function documentation
in the [GapAnalysis R folder](https://github.com/CIAT-DAPA/GapAnalysis/tree/master/R).**
