SNAP data QA/QC Shiny app R code

The about.R script uses a standard template for my Shiny apps to generate content for the app’s About page. It provides a brief description of the app and links to related resources.

        Downscaled observation-based historical data from the Climatological Research Unit (CRU 3.2) can be included in comparisons as well.</p>

        basic time series plots (not time series analysis), scatter plots, heat maps, various plots designed to highlight variability, and distributional plots.
        See the help section for more details on app usage, features, and limitations. Visit the Github page if you find a bug or other issue.
