read.eqs {REQS}

Import of EQS outputs into R

Description

This function reads EQS output files (.ets, .CBK and .ETP) into R and stores the results as objects.

Usage

read.eqs(file)

Arguments

file

The name (string) of the .ets file or the full path which the data are to be read from. If it does not contain an absolute path, the file name is relative to the current working directory, 'getwd()'. A .CBK and .ETP file have to be of the same name and in the same directory.

Details

The value list below provides objects for the full EQS output. If in EQS some objects are not computed, the corresponding values in R are NA.
