In MichaelFolkes/ctctools: Analytical tools For The Pacific Salmon Commission's Chinook Technical Committee.

Description

(ISBM/CYER) Import one or more ISBM index (*.pt) files.

Usage

readPT(filenames)

Arguments

filenames

A character vector. The names of the *.pt files for import.

Value

A list comprising elements that are also lists, one for each .pt file imported. Each sub list comprises six elements. Their names are: metadata, data.isbm, data.isbm.long, data.isbm.ages, data.bper, data.bper.long. The element metadata is a list of seven named vectors that include all the same information at the top of each .pt file. The element data.isbm is a data frame of the ISBM index data in the same format as found in the .pt file. The element data.isbm.long is a data frame and comprises the same ISBM index data reshaped into the more useful 'long' format. The age data are exluded from data.isbm.long but can be found in data.isbm.ages, which is a data frame in long format. The element data.bper is data frame of the base perior exploitation rate data (BPER), in the same format as found in the .pt file. The element data.bper.long is the same BPER data but in long format.
