augmentGrid {mtdesign}

Augment a grid of candidate designs with type 1 and type 2 error probabilities, expected sample sizes and probabilities of early termination

Description

Augment a grid of candidate designs with type 1 and type 2 error probabilities, expected sample sizes and probabilities of early termination

Usage

augmentGrid(d, parallel = TRUE, cores = NA, minChunkSize = 1e+05)

Arguments

d

a tibble created by 'createGrid'

parallel

use parallelisation if available

cores

the number of cores to use when parallelising. If <code>NA</code>, all available cores are requested

minChunkSize

The minimum size of the grid before paralellisation is attempted

Value

an augmented grid tibble

Usage Notes

Regardless of the value of 'parallel', parallelisation is only used if the size of the grid is greater than <code>chunkSize</code>. If paralellisation is requested and needed, an exception is thrown if the parallel package is not available.

Examples

x <- createGrid(p0 = 0.1, p1 = 0.30, alpha = 0.1, beta = 0.1, nMin = 24, nMax = 32) %>%
  augmentGrid(parallel = FALSE)
