fgeo.validate

Lifecycle: experimental Travis build status CRAN status

The goal of fgeo.validate is to validate ForestGEO tables. Specifically, it aims to meet these Requirements.

Installation

You can install the development version from GitHub with:

# install.packages("devtools")
devtools::install_github("forestgeo/fgeo.validate")

Example

This is a basic example which shows you how to solve a common problem:

library(fgeo.validate)
## basic example code

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.

  1. DFstatus is exactly the same as the status variable in ViewFullTable.

  2. 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:

  1. 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.

  1. Propagate the Rstatus D (dead) forward, even if the stem disappears in later censuses.

  2. G - “gone” - propagate forward (even if stem disappears in later censuses) until the stem is measured again in a later census.

  3. 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:

  1. P should NEVER follow any of the other Rstatuses. It should be the first Rstatus, or not appear at all.

  2. P should not go directly to G or D, without first going to A.

  3. D should never be followed by A or G.

  4. 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.
