eval_options {FIESTAutils}

List of population tables.

Description

Returns a list of user-supplied parameters and parameter values for data evaluation (FIA or custom) extraction to be supplied to *DB functions.

Usage

eval_options(
  Cur = FALSE,
  Endyr = NULL,
  Endyr.filter = NULL,
  All = FALSE,
  Type = "VOL",
  evalid = NULL,
  invyrs = NULL,
  measyrs = NULL,
  varCur = "INVYR",
  evalType = NULL,
  ...
)

Arguments

Cur

Logical. If eval='FIA': extract plots with most current evaluation. If eval='custom': extract the most current sampled plots in the database.

Endyr

Integer (YYYY). If eval='FIA', defines end year for extracting one or more FIA evaluation. If eval='custom', defines end year for extracting the most current sampled plots until.

Endyr.filter

Filter. If endyr != NULL, a filter to identify when to use measEndyr, such as areas or plots identified as being disturbed in a particular year. In this example, plots sampled after the disturbance will be excluded.

All

Logical. If eval='FIA': includes all evaluations in database (annual inventory only). If eval='custom': includes all years in database (annual inventory only).

Type

String vector. Evaluation types ('ALL','CURR','VOL','P2VEG', DWM','INV','CHNG','GRM','REGEN'). If eval='FIA', Type is equivalent to plots for FIA Evaluations where 'ALL' includes nonsampled plots; 'CURR' and 'VOL' include plots used for area or tree estimates, respectively; Type = 'GRM' includes plots used for growth, removals, mortality; and Type = 'CHNG' includes plots used for change estimates (See FIA database manual for regioin availability and/or differences (https://www.fia.fs.usda.gov/library/database-documentation/index.php) If eval='custom', the associated tables are extracted for each Type. Multiple Types are accepted.

evalid

Integer. Only eval='FIA': extract data for a specific evaluation period. See notes for more information about FIA Evaluations.

invyrs

Integer vector. eval='custom': defines specific inventory years of data (e.g., 2010:2015). See FIA manual for definition of INVYR.

measyrs

Integer vector. eval='custom': defines specific measurement years of data (e.g., 2010:2015).

varCur

String. Name of variable to use for most current plot ('MEASYEAR', 'INVYR').

evalType

Deprecated. Use Type instead.

...

For extendibility.

Details

If no parameters, an empty list is returned.

Value

A list of user-supplied parameters and parameter values for strata.
