EVALIDs in the FIA Database are used to reference data points associated with particular inventory years and evaluation types within a state (e.g. 2017 Current Volume in Michigan). They are often extraordinarily confusing for those not familiar for the FIA Database. With this in mind, rFIA has been designed to eliminate users dependence on identifying and specifying appropriate EVALIDs to produce desired estimates, and we therefore do not recommend users attempt to identify EVALIDs independently.
Any state
or year
specified must be present in db
to return associated EVALIDS.
A numeric vector containing the EVALIDs associated with states, years, or evaluation types specified.
