convertInitDesignToGrid | R Documentation |
This function takes an initial design – with rows being the observations
and columns standing for the dimensions (plus the corresponding objective)
– and adds an additional column to the data.frame
. This additional
column states the cell ID for each observation.

A data.frame
, which includes an additional column (cell.ID
)
compared to the initial design (init
). The cell.ID
will be a
value between 1 and prod(blocks)
.
# (1) create an initial design: X = t(replicate(n = 200, expr = runif(n = 5, min = -10, max = 10))) f = function(x) sum(x^2) y = apply(X = X, MARGIN = 1, FUN = f) init = data.frame(X, y = y) # (2) compute the cell mapping grid convertInitDesignToGrid(init = init, lower = -10, upper = 10, blocks = 20)
