Next Master Update Checklist

Implement some cv4, tarif, and sv632 equations (DF, WH, RC at least)

• [X] DF
• [X] WH
• [X] RC

Write test for generalized build_equations function

Write informal tests for merchantable volume, tarif, cv4, etc

Re-do sample with new changes

Update README with new changes

Change calc_cvts to calc_vol OR refactor calc_cvts to work with build_eq

• After these are done it will be ok to push to master

Create some test data using NVEL

A Random To-Do List

Maintenance & Improvements

[#C] Fix “AK_SECN” coefficient tables

• Tricky / improper formatting

[#B] Working equations lists needs formatting

• It would be nice if this list was more of a table type thing
• This would require editing bin/supported.R

[#B] Convert all csv’s to rda

[#A] More tests!

Calc_vol alignment check

• Check that when calc_vol is called on a dataframe, that the vector returned by calc_vol is correctly aligned with the original sample data
• This could be done by for-looping through the dataframe and calculating the volume via each record, then comparing equal to

New Features

[#B] Implement sofarchivetwood merchantable volume equations

[#B] Implement cv4 equations

• This will need either really long function definitions, or the ability to call other functions from the stored function string. The second option seems do-able and would clean the csv’s up quite a bit.

  The problem is that I need to access the original input region and spcd to fully identify the equation in the first place… (i.e. to get the correct coefficients).

  Got something working (on laptop forvol_dev/pupulate_with_funcs.R). It looks like I am able to build equations within function strings pretty easily. The next step is to figure out what is appropriate w/r/t notation and keeping functions readable.

Create forvol-specific citations csv

Ideas

Advanced usage methods

Equation builder

• Allow user to retrieve equation strings (see equation forms idea below)
• Allow user to easily input their own coefficients

Equation forms csv

• It is now clear that each ID from the FIA spreadsheets does not strictly correspond to an equation form, that said it will eventually be necessary to create key value pairs for equation forms and the functions themselves. This will be much simpler and cleaner, but will require a lot of work to reorganize and name them (ideally they will be named after the ciations)
