aggregateData: Aggregate and select data from Atlantis output

In r4atlantis/atlantisom: Generates Data Sets From Atlantis Scenarios

Aggregate and select data from Atlantis output

Description

subsets data based on defined columns, and sums over layers, but enter NA for layers to keep the column names the same. Currently, the function works for a vector of defined species and polygons.

Usage

aggregateData(
  dat,
  time,
  species,
  boxes,
  keepColumns = c("species", "agecl", "polygon", "time")
)

Arguments

dat	A data.frame of numbers-at-age from reading in the Atlantis output
time	A single value or a vector of time steps for a survey. Time steps are specified as integers.
species	A vector of character values, where each entry is a species name that is sampled in the survey.
boxes	A vector of polygons where the survey samples within each specified polygon.
keepColumns	A vector of character values, specifying which columns to keep for the returned data.frame. The default is c("species", "agecl", "polygon", "time").

Value

The function returns a subsetted matrix with the same columns as the input data, i.e.,:

• species

• agecl

• polygon

• layer

• time

• atoutput

Examples

dat <- data.frame(species = c(rep("spec1", 3*3),rep("spec2", 5*3)),
  agecl = c(rep(1:3, 3), rep(3:7, 3)),
  polygon = c(rep(1:3, each = 3), rep(1:3, each = 5)),
  layer = 1, time = 1)
dat$atoutput <- 10000/dat$agecl
tmp <- aggregateData(dat = dat, time = 1,
  species = c("spec1", "spec2"), boxes = 1:2)
rm(list = c("tmp", "dat"))
