In exact2x2: Exact Tests and Confidence Intervals for 2x2 Tables

Create grid for root search.

Description

Used with unirootGrid

Usage

power2grid(power2 = 3, from = 10, to = 1, dolog = TRUE)
power2gridRatio(power2 = 3)
power2gridDifference(power2 = 3)

Arguments

power2	positive integer, determines length of grid, length(grid)=1+2^power2
from	lowest value of grid
to	highest value of grid
dolog	logical, make grid equally spaced on the log scale?

Details

The function power2gridRatio gives a grid for searching from 0 to Inf equally spaced on the log scale, with about half of the observations from 0.5 to 2. and power2gridDifference gives an equally spaced grid for searching from -1 to 1.

Value

a vector for grid search of length 1+2^power2 for use in unirootGrid
