FilterMortByCondition: Filter FIA_mortality* by COND table rules

In bmcnellis/RSFIA: FIA Tree Mortality Analysis

Description

Some conditions needs to be filtered out - running this trims down the dataset.

Usage

FilterMortByCondition(dir = getwd(), data = NULL, plot_type = "prev",
  db_ver = 7.2, sub_dom_cutoff = 0.75)

Arguments

dir	Directory of *_COND.csv files
plot_type	Either 'prev' for PREV_PLT_CN, or 'post' for PLT_CN
db_ver	Database version

Details

Rules relevant to methods:

Conditions included had to meet COND_STATUS_CD == 1, i.e. accessible forest land

For plots with more than one forest type, sub-dominant (< sub_dom_cutoff) forest types were excluded. If, after applying this filter, plots still had more than one forest type, plots were excluded.

For plots with multiple conditions, condition values were averaged.
