Parse, format, and validate international phone
    numbers using Google's 'libphonenumber' java library,
    <https://github.com/google/libphonenumber>.

Collects 'libphonenumber' jars required for the
    'dialr' package.

Many models contain tuning parameters (i.e. parameters that
    cannot be directly estimated from the data). These tools can be used
    to define objects for creating, simulating, or validating values for
    such parameters.

Visualize one-factor data frame. 
  Beads plot consists of diamonds of each factor of each data series. 
  A diamond indicates average and range. 
  Look over a data frame with many numeric columns and a factor column.

Provides a 'dibble' that implements data cubes (derived from 
    'dimensional tibble'), and allows broadcasting by dimensional names.

This package provides utilities to calculate the probabilities of various dice-rolling events, such as the probability of rolling a four-sided die six times and getting a 4, a 3, and either a 1 or 2 among the six rolls (in any order); the probability of rolling two six-sided dice three times and getting a 10 on the first roll, followed by a 4 on the second roll, followed by anything but a 7 on the third roll; or the probabilities of each possible sum of rolling five six-sided dice, dropping the lowest two rolls, and summing the remaining dice.

Space-Filling Designs and space-filling criteria (distance-based and uniformity-based), with emphasis to computer experiments; <doi:10.18637/jss.v065.i11>.

Estimation, validation and prediction of models of different types : linear models, additive models, MARS,PolyMARS and Kriging.

Estimation, validation and prediction of kriging models. Important functions : km, print.km, plot.km, predict.km.

Efficient Global Optimization (EGO) algorithm as described in "Roustant et al. (2012)" <doi:10.18637/jss.v051.i01> and adaptations for problems with noise ("Picheny and Ginsbourger, 2012") <doi:10.1016/j.csda.2013.03.018>, parallel infill, and problems with constraints.
