mef 9cd84d0bf9 (math/R-compositions) Updated 1.40.2 to 2.0.2
Version 2.0-1.9001

Minor changes / Bugfixes:
  * functions that do not work with sticky classes are now wrapped
  (e.g. `anova()`)

Version 2.0-1.9000

Major change: sticky classes!
  Now objects of compositional classes do not miss their class
  when subsetting. For example, if `x` is an "acomp" object,
  x[1:2,] will also be an "acomp" object. Selection of columns work
  as well, but it is a bit more tricky. Check ?`[.acomp` for
  details. You can get skip this behaviour by setting
  setStickyClassOption(FALSE). The dollar notation `$` also works!

Added:
  * Limited support for using compositions classes as formal S4
  classes, for instance in slots of S4 classes expecting a
  "data.frame" or a "structure" (matrix or array).
  * self-invertibility: now "rmult" objects created by any
  transformation (cdt, clr, cpt, idt, ilr, ipt, iit, ilt, alr,
  apt) remember the original data and the transformation between
  them, and can be back-transformed with `backtransform`.
  * added cdt and idt methods for objects of class "factor" (returning
  the contrasts and their ipt transformation), and for "data.frame"
  objects (exploiting the attribute "origClass" if they have it).
  * `pwlr()`: pairwise logratio transformation (and inverse: `pwlrInv()`)
  * `pwlrPlot()`: pairwise logratio plots vs covariables, both as explained
   and as explanatory variables. This makes use of the ability of plot(x~y)
  to react to the nature of `x` and `y` to create scatterplots, boxplots
  and spineplots.
  * transformation functions between variation and clrvar: variation2clrvar
  and clrvar2variation
  * `split()` methods for compositional classes
  * new panels for filling `pairs()` plots with boxplots, densities,
  kde2d-densities, etc...: check ?vp.kde2dplot

Minor Changes:
  * the function to fit linear models of coregionalisation is now called
  `fit.lmc()`; use full name specification with it! `compositions::fit.lmc()`

Bugfixes:
  * bug in subsetting of one-column rmult object corected
