rebinSizeFreqs.OldFormat: Re-bin size frequencies from annual ADF&G observed size...

In wStockhausen/tcsamCrabFisheryData: Functions to process ADFG fishery data for the Tanner crab assessment.

Description

Function to re-bin and export size frequencies based on annual ADF&G 1-mm size bin counts as csv files.

Usage

rebinSizeFreqs.OldFormat(tbl = NULL, cutpts = seq(from = 25, to = 185, by =
  5), truncate.low = TRUE, truncate.high = FALSE, csv.base = NULL)

Arguments

tbl	- dataframe derived from old-format ADF&G observed size frequencies csv file, or csv file itself
cutpts	- vector of cut points for binning
truncate.low	- flag (T/F) to exclude sizes smaller than the 1st cutpoint
truncate.high	- flag (T/F) to exclude sizes larger than the last cutpoint
csv.base	- filename base for output csv files

Details

This function takes a dataframe derived from an old-format ADF&G observed size frequencies file, bins it, and converts it to wide- and long-format size frequency dataframes, as well as an associated table of sample sizes. In the old format, each file represents total numbers of at-sea observer-measured crabs for a single year, classified by shell condition categories 'newsoft', 'pliable', 'new', 'old' and 'very old' (each a column), as well as by 'sex' and 'size' (columns).

Value

list with 3 elements * long - size frequencies in long format * wide - size frquencies in wide format * sample.size - associated sample sizes
