diversity indices at different sampling levels.

This package is made for solving cubic and quartic
equations and analyze the distribution of the data that R user
provide. The package contains function Cubic and Quart for
equations and all kinds of functions for distributions analysis
which have format as is.xxdistrbution and if you don't know
which distribution to judge, use function is.dt.

The package involves two kinds of functions. One is to
solve cubic and quartic equations. The other is to analyse the
distribution of a set of given data.  The function Cubic and
Quart are for solving equations. The function which has the
form as "is.xxdistribution" is for analysing whether the data
obeys the xxdistrbution. If you don not know which distribution
to judge, use function is.dt.

The DnE package involves functions to analyse the distribution of a set of given data. The basic idea of the analysis is chi-squared test. Functions which have the form as "is.xxdistribution" are used to analyse whether the data obeys the xxdistrbution. If you do not know which distribution to judge, use function is.dt().

Creation of Arrays by Mixed Integer Programming
'CRAN' package 'DoE.base' and non-'CRAN' packages 'gurobi' and 'Rmosek' (newer version than that on 'CRAN') are enhanced with functionality for the creation of optimized arrays for experimentation, where optimization is in terms of generalized minimum aberration. It is also possible to optimally extend existing arrays to larger run size. Optimization requires the availability of at least one of the commercial products 'Gurobi' or 'Mosek' (free academic licenses available for both). For installing 'Gurobi' and its R package 'gurobi', follow instructions at <http://www.gurobi.com/downloads/gurobi-optimizer> and <http://www.gurobi.com/documentation/7.5/refman/r_api_overview.html>. For installing 'Mosek' and its R package 'Rmosek', follow instructions at <https://www.mosek.com/downloads/> and <http://docs.mosek.com/8.1/rmosek/install-interface.html>.
