# S3 method for class 'summary.optcheck'
print(x, digits = max(3L, getOption("digits") - 3L), n = 5L, ...)

Arguments

x

Object of class optcheck or summary.optcheck, currently returned by optim_proj(), optim_refit(), or a summary of either of those calls.

digits

Number of digits to display.

n

Details

The print methods for optcheck and summary.optcheck objects both display three-column matrix, consisting of the potential solution (xsol), the absolute difference between it and the optimal solution (xopt) return by either optim_proj() and optim_refit(), and the relative difference (R = (xopt - xsol)/|xsol|). Only the elemnts corresponding to the top-n relative differences are displayed.
