bsmData: Import Data for BSM

In tmelliott/bsm: Bayesian Selectivity Modelling of Fisheries Trawl Data

Description

This function handles manipulation of a provided data set (in the form of a data frame, from read.csv or similar) to a form that can be used by other bsmData functions.

Usage

bsmData(y1, y2, n, length, length.unit = NULL, haul, q1, q2, paired = FALSE,
  data = NULL, ...)

## S3 method for class 'bsmdata'
print(x, ...)

Arguments

y1	the count for the codend or experimental trawl
y2	the count fo the cover or control trawl
n	the total fish caught in the trawl
length	the length of fish
length.unit	the unit of length measurements
haul	the haul id
q1	sampling fraction for codend/experimental trawl
q2	sampling fraction for cover/experimental trawl
paired	logical, is the data from a paired trawl?
data	the name of the data frame. If NULL, then the other supplied argument must be vectors. Otherwise if df is supplied, then the other arguments are the variable names.
...	additional variables can be passed to the object, such as weights, mesh sizes, and any other covariates to be used in later modelling
x	a bsmData object

Details

The simplest use is where a data frame is provided, and the required column names are specified as function arguments.

It is also possible to supply vectors and no data frame.

Value

An object of class bsmdf. This is a list with necessary information, and is what should be supplied as the data argument to other bsmData functions.

Methods (by generic)

• print: Print information about the data object
