multiDimLHS: Multidimensional Latin Hypercube Sampling (LHS) generation

Description

The function generates or augments a multidimensional design in a hyperbox.

Usage

multiDimLHS(N, lb, ub, method = c("randomLHS", "maximinLHS",
  "augmentLHS"), X = NULL, type = c("list", "matrix"))

Arguments

N

number of points to randomly select or augment an existing sample set

lb

lower bounds defining the (hyper)box of the parameter search space

ub

upper bounds defining the (hyper)box of the parameter search space

method

type of sampling, `randomLHS`, `maximinLHS` or `augmentLHS`

X

optional, matrix of existing sample points, NULL (default), for augmentation only

type

either "list" or "matrix" as return type

Value

Either return a list or matrix of sampled vectors or newly generated points if an existing sample set was to be augmented.

Examples

# NOT RUN {
data(normal)
# generate a design
X <- multiDimLHS(N=5,qsd$lower,qsd$upper,type="matrix")

# augment design X 
rbind(X,multiDimLHS(N=1,qsd$lower,qsd$upper,X=X,
				method="augmentLHS",type="matrix"))
