Builds tables with customizable rows. Users can specify the type
             of data to use for each row, as well as how to handle missing
             data and the types of comparison tests to run on the table
             columns.

Implementation of functions for fitting taper curves (a semiparametric 
  linear mixed effects taper model) to diameter measurements along stems. Further 
  functions are provided to estimate the uncertainty around the predicted curves, 
  to calculate timber volume (also by sections) and marginal (e.g., upper) diameters. 
  For cases where tree heights are not measured, methods for estimating
  additional variance in volume predictions resulting from uncertainties in
  tree height models (tariffs) are provided.  The example data include the taper 
  curve parameters for Norway spruce used in the 3rd German NFI fitted to 380 trees 
  and a subset of section-wise diameter measurements of these trees. The functions 
  implemented here are detailed in Kublin, E., Breidenbach, J., Kaendler, G. (2013)
  <doi:10.1007/s10342-013-0715-0>.

Providing new german-wide 'TapeR' Models and functions for their 
  evaluation. Included are the most common tree species in Germany (Norway 
  spruce, Scots pine, European larch, Douglas fir, Silver fir as well as 
  European beech, Common/Sessile oak and Red oak). Many other species are mapped
  to them so that 36 tree species / groups can be processed. Single trees are 
  defined by species code, one or multiple diameters in arbitrary measuring 
  height and tree height. The functions then provide information on diameters 
  along the stem, bark thickness, height of diameters, volume of the total or 
  parts of the trunk and total and component above-ground biomass. It is also 
  possible to calculate assortments from the taper curves. Uncertainty 
  information is provided for diameter, volume and component biomass estimation.

Wrapper for using 'tapkee' command line utility,
 it allows to run it from inside R and catch the results for further analysis and plotting.
 'Tapkee' is a program for fast dimension reduction, see 'package?tapkee' and <http://tapkee.lisitsyn.me/>
 for installation and other details.
