makebox: Make a box with bounds

In andrewpbray/lmmoptim: Optimization routine for linear mixed models

Description

Given the limits of the box, calculate its status relative to each line and calculate the bounds on the objective function within that box.

Usage

makebox(lims.sigsqe = NA, lims.sigsqs = NA, status = NA, lines)

Arguments

lims.sigsqe	numeric vector of length 2 of the form c(lower, upper) containing the x-limits of the box.
lims.sigsqs	numeric vector of length 2 of the form c(lower, upper). containing the y-limits of the box.
status	factor of length of lines denoting the location of the box relative to each line. If the box has a parent, these correspond to the status of that parent. The levels are {above, below, straddle}.
lines	dataframe containing the constants that define the shape of each term in the sum. Output from findlines.

Value

A list containing:

• limits of the box in σ^2_e (numeric vector of length 2)

• limits of the box in σ^2_s (numeric vector of length 2)

• the status of the box relative to each line (factor of length of the number of terms in the sum)

• the bounds on the objective function (numeric vector of length 2 of the form c(lower, upper))
