Tabulate abundance by length and age with additional info on the margin

Description

Tabulate abundance by length and age with additional marginal info consisting of:

• Marginal sums of abundance and biomass for length categories and age groups

• Mean length at age and mean weight at length and age

• Percentage age distribution

Usage

tabulate_byla(fishData, nScale = 1e+06, bScale = nScale)

Arguments

fishData	data.frame of numbers and biomass by length and age
nScale,	bScale scaling factor, default one million

Details

Table traditionally included in the reports of the Northern Pelagic and Blue Whiting and the North Western Working Groups of ICES as well as in survey reports.

Value

List of matrices of abundance by length and age hybridized with other info on the margin, for the stock combined (all) and immature (imm) and mature (mat) parts of the stock.
