fiaRI

Subset of the Forest Inventory and Analysis Database for the state of Rhode Island. Reporting years range from 2013 - 2018. Specify <code>fiaRI</code> as the <code>db</code> argument in any <code>rFIA</code> function to produce estimates for the state of Rhode Island. NOTE: the fiaRI object was updated in v1.1.0 to reflect changes in the FIA Database that took place since creation of the original object.
Download other subsets of the FIA Database from the FIA Datamart: <a href="https://apps.fs.usda.gov/fia/datamart/datamart.html">https://apps.fs.usda.gov/fia/datamart/datamart.html</a>. Once downloaded, unzip the directory, and read into R using <code>readFIA</code>.

The goal of 'rFIA' is to increase the accessibility and use of the United States Forest Services (USFS) Forest Inventory and Analysis (FIA) Database by providing a user-friendly, open source toolkit to easily query and analyze FIA Data. Designed to accommodate a wide range of potential user objectives, 'rFIA' simplifies the estimation of forest variables from the FIA Database and allows all R users (experts and newcomers alike) to unlock the flexibility inherent to the Enhanced FIA design. Specifically, 'rFIA' improves accessibility to the spatial-temporal estimation capacity of the FIA Database by producing space-time indexed summaries of forest variables within user-defined population boundaries. Direct integration with other popular R packages (e.g., 'dplyr', 'tidyr', and 'sf') facilitates efficient space-time query and data summary, and supports common data representations and API design. The package implements design-based estimation procedures outlined by Bechtold & Patterson (2005) <doi:10.2737/SRS-GTR-80>, and has been validated against estimates and sampling errors produced by FIA 'EVALIDator'. Current development is focused on the implementation of spatially-enabled model-assisted and model-based estimators to improve population, change, and ratio estimates.
