Centered log ratio (clr) transformation of data

It would be useful to have a function that is able to do logratio transformations (additive logratio (alr), centered logration (clr) and Isometric logratio (ilr) transformations). It is an important step in order to open up closed data (e.g. compositional data) before doing multivariate analyses. It is frustrating that I cannot do that with XLSTAT and have to search for other software
