功能\作用概述:

空间填充设计（SFD）和空间填充标准（基于距离和基于均匀性）。

语法\用法：

# **********************
# Designs of experiments

# A maximum entropy design with 20 points in [0,1]^2

# Change the dimnames, adjust to range (-10, 10) and round to 2 digits
xDRDN(p, letter = "T", dgts = 2, range = c(-10, 10))

# in 8D. All pairs of dimensions are tried to detect the worst defect
# (according to the specified goodness-of-fit statistic).
d n rss type="l", col="red")

# avoid this defect with scrambling ?
# 1. Faure-Tezuka scrambling (type "?sobol" for more details and options)
