Change Save File Location

Use this to change the saveFile parameter in a pre-existing bayesOpt object.

Usage

changeSaveFile(optObj, saveFile = NULL)

Arguments

optObj

An object of class bayesOpt

saveFile

A filepath stored as a character. Must include the filename and extension as a .RDS.

Value

The same optObj with the updated saveFile.

Examples

scoringFunction <- function(x) {
  a <- exp(-(2-x)^2)*1.5
  b <- exp(-(4-x)^2)*2
  c <- exp(-(6-x)^2)*1
  return(list(Score = a+b+c))
}

bounds <- list(x = c(0,8))

Results <- bayesOpt(
    FUN = scoringFunction
  , bounds = bounds
  , initPoints = 3
  , iters.n = 2
  , gsPoints = 10
  , saveFile = tempfile(fileext = ".RDS")
