In eeholmes/VRAPCpp: VRAP 2nd edition with C++ for RER and Viability Computations

VRAPS

R package for VRAP rewrite

To install

library(devtools)
#tell devtools build only for your machine: 32- or 64-bit
#needed because C++ code in the VRAP 2.0 package
options(devtools.install.args = "--no-multiarch")
#VRAP 2.0
install_github("eeholmes/VRAPCpp")
#VRAP 1.0
install_github("eeholmes/VRAP")

The vignettes in the package are not built by default as that would take a long time. If you want them built add build_vignettes = TRUE to the install_github call. However, the normal procedure for a package is for the package developer to build the vignettes locally and then put the Rmd and html (from knit) files in the inst/doc folder which will then get uploaded to github.

To build all the vignettes in the vignette folder in the package and put the files into inst/doc. Use

#note "." must be the base level of the package for this to work.
require(devtools)
build_vignettes()

Or knit the vignette and manually move the html file and Rmd file into the inst/doc folder.

Vignettes

The package has vignettes that discuss the background of VRAP and show how to use it. To view the vignettes available use:

browseVignettes(package="VRAPS")

You can open a vignette rmarkdown file using

vignette_rmd_file = "Background.Rmd"
fpath <- system.file("doc", vignette_rmd_file, package="VRAPS")
file.open(fpath)

Notes

• Parameters that mean the same thing in VRAP 1.0 and VRAP 2.0 have the same name.
• The exception is 'prod' and 'cap' used instead of 'BSRa' and 'BSRb' since 'prod' and 'cap' are easier to understand and used in DM.
• The "Buffer" jargon from VRAP 1.0 is removed since VRAP 2.0 uses ER/Pop start and end with a specified step size. The VRAP 2.0 terms are StepSize, StepStart, StepEnd and StepNum. However in rav files, the step size, start and end are defined as a fraction of base ER or Pop capacity to keep the VRAP 2.0 and VRAP 1.0 rav files the same.
• StepNum in VRAP 2.0 and BufMax in VRAP 2.0 are both the total number of target ERs (or Pops) simulations. It is not "total - 1" (as in Martin's first draft of VRAP 2.0 code).

to do

• Martin: Add totAEQmort to RunSims2C(). I have defined at top. But simFish() needs to be altered to return it. See changes to RunSims2R().

• I did not do the BYHR SummaryStats. I wasn't sure anyone used them and didn't want to add a bunch more code.

Running a demo of the VRAP 1.0 emmulation

setwd("vignette_files")
out = Main.VRAP1("tmp.rav")
out = Main.VRAP1("tmp.rav", version="C")

That will run tmp.rav through Main.VRAP1() and make all the VRAP 1.0 output files. Note, Martin needs to add totAEQmort to simFish() before this will run.
