The goal of fgeo.validate is to validate ForestGEO tables. Specifically, it aims to meet these Requirements.
You can install the development version from GitHub with:
# install.packages("devtools")
devtools::install_github("forestgeo/fgeo.validate")
This is a basic example which shows you how to solve a common problem:
library(fgeo.validate)

Subject: RE: Building R stem tables for the upcomming workshop
When making the R stem tables, please note the following comments when determining the status variable.
-
DFstatus is exactly the same as the status variable in ViewFullTable.
-
The status variable in the R tables is calculated as follows for stems:
status_in_viewfulltable | status_after_rtbl |
---|---|
alive | A |
dead | D |
broken below or stem dead | G |
missing | M |
Also, do the following:
- Give an Rstatus of P -“prior”, if a stem does not appear in the first censuses, i.e. stem is first measured in a later census.
Propagate status == P
forward in all censuses until it first appears.
-
Propagate the Rstatus D (dead) forward, even if the stem disappears in later censuses.
-
G - “gone” - propagate forward (even if stem disappears in later censuses) until the stem is measured again in a later census.
-
If a stem was dead in a census, then later found alive, go back and change all the Rstatus ‘D’ to ‘A’.
Stems may go through the following Rstatuses and in this order:
P (prior) -> A (alive) -> G (gone) -> D (dead)
P, G, and/or D may be missing.
Problems that have to be fixed in the Rstatus sequence:
-
P should NEVER follow any of the other Rstatuses. It should be the first Rstatus, or not appear at all.
-
P should not go directly to G or D, without first going to A.
-
D should never be followed by A or G.
-
Stems should not start with a G, they should start with P or A. Somemes they start with a D when the site tags and measures dead stems
The folder called “onecensus” contains the data from sites for which I have one census only. You may not need to make R tables for these sites, since the R tables that already exist should be fine. You may still want to make them to compare with those that are on the server.
